But Sales are the single most important thing for any Publisher or Developer.
Sales dictate the future of the Publisher & the scope of future games for the developer.
If DA:I doesn't sell enough to please the Suits, We won't see a Dragon Age game of it's scale again. That's the problem here
Why would EA give bioware another 60 + million dollars for a franchise that doesn't sell 4 million+ ? They won't, we will be back to 2 year Dev Cycles at best.
Add to that the fact that Pretty much ALL of the November Big Boys have more established brands & Bigger User bases than Dragon Age, that pretty much takes the Mainstream gamer out of the Equation right then & there.
Some how I doubt that there are 3 to 4 Million DA fans out there to pick up the slack for the first (& most important) couple of Weeks that DA:I is on store shelves.
It's untimely to say the least, but I'm interested to see where the money falls come the new year 
Finally someone who gets it.
Everyone talks about DAI having it unique fanbase and what not, but that alone isnt what Electronic Arts wants. I mean, why do you think Bioware scaled back the combat in DAI and even DA2 from DAO? So that casuals can play it. Why do you think there is multiplayer? So that the multiplayer crowd from other cames would have a "reason" to buy the game.
If EA was 100% fine with DAI JUST cateering to Bioware/RPG fans, then DAI would NOT have multiplayer and the combat would be more like DAO instead of the DA2's press a button and watch something awesome happen.
Bioware fans will buy DAI no matter what.
RPG fans for the most part will buy DAI.
What about the casual gamer walking into a Walmart or GameStop with $65 ready to buy a game? DAI is sitting on the shelf but so is GTA V (PS4/Xbone), so is Assassin's Creed, so is Halo, and so is Call of Duty. There is a VERY slim chance that this casual dudebro gamer will choose to spend his $65 on DAI over these other, more mainstream and established games as it would be a safer buy for him.
This is the problem that I am talking about. If this were Mass Effect 4, then things would be different. But it isnt. DAI will sell in the millions, but how much? Releasing in early October would have allowed it to be only huge AAA game. EA/Bioware would own the internet marketing and TV marketing. Casuals would have no choice but to understand what DAI is and how "cool" it would be to play. However in November, the marketing would be so saturated and so convoluted by Activion's COD, Microsoft's Halo, and Rockstar's GTA V, I just do not see how DAI can stand above all of that. Especially during Holidays season with Black Friday being just around the corner. Moms and Dads, friends, and families would be more comfortable with the more established brand in Assssin's Creed/Halo/COD/GTA to buy for their loved ones than DAI.
I know you guys are serious Bioware/Dragon Age fanboys/fangirls and you may want to deny certain scenarios. But if you want serious and high budget DLC like the Citadel DLC for DAI, or even for DA4 to have the production makeup like DAI, then you better hope that DAI sells A LOT. However, releasing during a time with other MORE established brands during Holiday Season is kinda scary. This is why October was the better bet. Yes, it gave Bioware more time to "polish" the game in terms of the Keep, single player, and multiplayer, but in the end, how much would this cost them in terms of product placement?
I think the main problem is not in players ability to pay for games, but in the amount of attention that they can pay to something. Im talking about promo compaign that expiriens its peak right at launch. Lots of trailers, interviews and ads everywhere - it's kind of overhelming. Now imagine when there is 3-4 AAA launching in just a few weeks. The effectivness of promo campaign will be low. That's the main reason.
