Hmm, if it were up to me, at this point, I'd actually sort of be thinking that there isnt really much of a choice. Now granted, I dont have all of the info and knowledge you do when it comes to stuff like this, but what I see is two possible issues:
1, you go with the EA route, and some problems may pop up of course... people that dont like dealing with EA, or people that dont understand what it means and flip the heck out when bugs appear. Stuff like that. Those are definite issues.
2, you go the November route.... and get utterly overwhelmed by it. At least with the EA route, people can buy the game. However, they cant do that at all if they just blew all of their money on the major releases. Something like Battlefield in particular is enough by itself; that one is frankly going to be SO huge that even if it were JUST that game by itself, I still would say "there isnt really any choice here". But even worse, it's NOT the only one. This is sort of a "worst case scenario" here.
Though, again with Battlefield, my impression of it is that the time around it's release isnt going to be the only period of time it affects; it might stretch out for a loooooong while after that, as people get utterly addicted to it, and dont play/buy anything else for quite some time. So that.... just sounds even worse, really. Bah.
I mean, you remember how it went the last time this happened. Bionic Dues, wasnt it? A game that turned out really well, had the potential to do really well, and to me, SHOULD have done really well... but went up against a major release, and was ignored. And that was a game with a shorter (much shorter) development time and smaller budget, yeah? My concern is: Can you guys actually afford to have this one go completely down the drain like that? I know how bad that sounds, but this game has also had a LONG development time, and I mentally associate that with "massive spending".
It's not an easy choice to make, and I seriously doubt you guys are the only ones facing this particular decision and problem right now... these games are going to probably screw with a ton of other things that might have had the chance to do well, if left somewhat alone. I dont think there's any easy way out of it, and what options there are, are both damaging. But the second one doesnt just seem damaging to me, it seems more of a game killer. There's just too much to go up against there, too many other very expensive things that have been hyped to hell for a LONG time, and that people will definitely be buying in droves.
So.... yeah, that's just my current thoughts on that choice overall. Again, I wish I had something more useful to say, but no matter how I look at it it just doesnt seem like a very good situation at all.
