My guess is Fall 2011.
Once the decision was made to move towards a full blown sequel rather than an expansion pack the budget changed (translation: Impulse sale to GME provided a lot of capital and we decided to spare no expense).
Hm,, so we are calling it a full blown sequel now? I totally missed that. I'd be careful about calling it that because it is still in many ways the same game, AFAIK. Are there significant new art assets? New music? New sound? Major new features? I really like everything that we have seen of FE so far, but it still seems like more of a big expansion or significant overhaul than 'full blown sequel.' Then again, the whole 'expansion pack' concept has become very blurred in recent years, especially with the advent of DLC. Maybe I'm just mincing words. Anyways, I guess the only other thing besides the above that would define it as a sequel or not would be the price point. Has that changed? Will it be sold at full price? I know many of us are supposed to get it for free (still have a hard time believing that, but hey - like others have said, its what makes Stardock a company I believe in). but for that that don't, will they be asked to pay $40-$60 like most modern full price games? Or will it be priced more like an expansion pack?
