"DA4" is not "DA4"

They already confirm the DA Tactics game has been scrapped.

Actually Mike just said he wasn't working on one.

They also said that if they did do one it would not replace a main entry of the series.

Still, it seems unlikely that they will make one except in the distant future.

It's probably another of those Failbetter browser games like The Cast Court.

Possibly. I don't think I'd mind that terribly much since I did like the Last Court. It had some annoying mechanics but I found it otherwise enjoyable and humorous. 

No, it will have it's own seperate name

If it is not an RPG then I do not really care.......

Person he was responding to with that tweet specifically asked if DA4 would be retconning Trespasser.

Like with DAI.

Yikes. Why would anyone think that was possible?

We know the team is working on something Dragon Agey. We know it's not a tactics game because Mark said as much. We're sure it's not a traditional expansion because Mark also said something like there isn't enough of a pay-off for making expansions, and Trespasser was sort of an expansion shrunk down to dlc size. So, unless they are doing something they have never done before, or (this is just a for instance) are making something smaller in scale like DA2 (without the recycled areas...hopefully) then assuming that they're working on the "4th main game in the series" is all anyone can do.

I'll admit the way Mike says "4th main game in the series" made me pause as well, but he's probably just trying to mess with our minds. 

I was not expecting them to reply, and in my view that was the only way to have Inquisitor as protagonist (which came up as a part of a chat in one of the threads on this forum) so I was curious if it was theoretically even a possibility. I did not think so, and, to my surprise, it was responded to with a definitive "no". I guess, they do want to disseminate information through Twitter,

This article seems to be of about as informed and as factual as any post in this thread. It is based of the same twitter responces as quoted here. The rest appears to be conjunction b/c they do not quote any other sources.
