yeah public as in strict NDAs and a selection process.
you guys are what qduffy refer to as their "most rabid fans". i mean i like the game myself but i'm not going to defend it if it sucks. the fact that they don't want to have something as common as an open beta (which is more of a 'try before you buy' kinda thing nowadays) sends off a serious red flag. someone else mentioned that maybe it's because SEGA doesn't want to lose pre-orders - and that's exactly the point. what would cause them to worry about that? maybe the game itself isn't that good? it shows a lack of confidence in their product.
I think the decision is all up to SEGA. I doubt anyone at SEGA even know what the game is like. Sounds like a corporate/publisher decision. Doesn't indicate if there's something to worry about WFA.
The game release lost preorders at launch maybe due to the lack of so many normal/modern RTS features (chat rooms, custom games, leaderboards, etc.), plus the hard history of this game (THQ going bankrupt, etc.).
