Am I the only one looking forward to the scanning device?

The first time through scanning won't bother me at all. After that? I will have to see how it works.

Can't wait to explore though.

no, i don't want another boring expansion that we never get to see and just walking acros huge boring maps to scavenge tousands of shards or materials
i want a good interesting story, just like ME1 or ME2
i don't care about exploring huge maps
a litle bit of exploration when arriving a new planet to see if an outpost or lab or civilization can be built there but nothing more

I mean here is the point though I think it all comes down to balance and how you do things.  DA I gets panned a lot of times for the quality of its side quests and the quality of its exploration content and for the content of its story.  And I...disagree really.  DA I had a lot of good side quests in it.  And a lot of DA Is side quests were fun.  The issue is one of balance and reptition.  I did not mind doing the side quests but I minded doing six side quests involving the rings.  I did ot mind doing the rifts, I minded doing it seventy times, I did not mind even doing the Shards really...I minded doing it over and over and over again.  The more you repeat something, the more boring it gets. 

I'm looking forward to it a little, but like someone else said I hope we aren't forced to spam it through the whole game.

As for the mechanic itself, I'll just have to see, but it looks cool in theory.

But the main thing I would be excited about is the idea of my Ryder getting to geek out about scanning things and exploring/learning new things, possibly more if you put points into upgrading scanning (which I think you can). We'll see if that is possible.

Something I was thinking about is that I think BW may have learned from all the crap they got from fans about not liking having to gather/mine/kill animals/kill people for mats. Tinfoil hat theory here but I really think we are going to be scanning a lot of different things rather than the synonym of picking up every elfroot we can find. Like I am thinking that the way to look at it is that once we know where the material is, we have access to it. Like I think that there will be fewer things to scan, but what we do scan will be more substantial. Another theory is that when we scan X amount of a certain thing then a pod drops giving us access to resources of that thing - we gain knowledge of that things properties and learn from it to allow us to create something new... or something..

From your lips to devs' ears, amen.

I could do without it...or less of it. If it's actually used to trigger story with real cutscenes, no issue there. However, the scanning lithium from the gameplay trailer screams elfroot to me, and that is the very definition of tedium. IMO it should be something that we have to use infrequently with the reward primarily being story content. Not so interested in scouring the planet side for an hour just to craft those nifty +1 butt straps.

It's going to be like Elfroot isn't it?

I agree with those criticisms... to an extent. 

DAI had huge, beautiful areas, but they felt very shallow. 90% of the time all you were actually doing were the same four quests (find the shards, collect stuff, kill x, close rifts). Some areas had cool side missions, like Crestwood, the Dalish had a cool mission where you had to catch a golden Halla and Dragon fights were fun. But ultimately none of it reached the strength of, say, the poetic treant we met in Origins, the political side-missions of Orzammar, finding a pet Nug for Leliana or guiding the blind templar through the ruined alienage building. Those missions stuck with me all these years later.

Basically, there were few fun and interesting NPC's or situations in the side content. Or, at least, finding them required sifting through hours of dull fetch quests. I remember excitedly discovering those ruins in the Oasis in Inquisition... only to find out that to progress through it you had to collect rift shards. So even what seemed like a fun exploration mission required tedious grinding. 

The main story missions were good, but the storyline felt too short considering the absurd size of the open world and hundreds of dull and repetitive quests. The game would have been much better if there were 2-3 less zones, more interesting content in the remaining zones, and an extra storyline mission. 

Another issue is that the main storyline and companion quests were oftentimes too detached from the open world. The most memorable missions: The Winter Palace, the Mages/Templars, the Elven Ruins, the final battle... none of them took place in or near the open world zones but in unique instances. Usually side quests are something you do alongside the main story, but Inquisitions didn't even take place in the same area. Many areas literally existed for no other purpose than side missions and had no relevance to the main storyline at all, which was very strange. 

Witcher Sense, Detective Mode, Eagle Vision, Survival Instinct, Whatever Quantum Break Called It, 'Sonar' or something in DA:I? It's getting old
