Well, take with a mountainous grain of salt, but I think Famousmortimer on GAF claimed Sony gave EA a recent presentation how much more Titanfall would have sold on PS3/PS4, and that it dwarfs what MS paid them. And that EA is in full "we're sorry Sony" mode.
Again, it's GAF, but it seems to make sense. Titanfall should have at least doubled console sales by being on Sony platforms, if not more given the success of PS4, and it's hard to see MS matching that kind of cash.
Whatever, it was a bold and smart move by MS to lock that up when they saw a chance.
I dont think EA expected the early pummeling PS4 put on Xbox One, either, presumably.
Edit: whoops, I see I'm just recapping what Bonobo said...
how ? There are what 6 m ps4s out in the wild ? Vs 4m or so xbox ones , how much more could it have possibly sold. Remember the take home per game is less than $30 bucks for EA . So even if we say it could sell 2m more that would only be 60m bucks . Doesn't seem like a lot of money on the table and who knows ifa nyone would care about the game if MS didn't have to push it like they did for the last year ?
