With all that happened I am honestly just surprised (as much as I hate third party exclusives) that Battlefront ended up a PS co-marketing title, now that we know they got the COD deal.
I think the situation between Activision/ COD and Sony has happened somewhat organically between their existing relations (long term partnership with Destiny, and already back on the PS3 with Diablo III...), but then also with EA becoming such a core partner for the XB1's launch and post launch support (including EA Access), it might have seemed natural to align themelves with Sony while the PS4 became #1 next gen platform WW I guess.
But then again, I wonder what was EA's logic with Battlefront (beside prefering the top selling console) in signing co marketing with Sony, while they have pushed the XB1 so much (with, among other things, that multi-million $ deal around NFL). Trying to make nice with Sony maybe? Or could Sony have circumvented them on some level and made a deal with Lucasfilm/ Disney directly, which gave them some "weight" in getting Battlefront? (cf the on stage talk around the reveal of Disney Infinity 3.0 Star Wars) :shrug:
I just find it weird that Sony ends up with not one, or two, but three futuristic FPS (with Destiny) being promoted for PS4 between September and November.
On the sales front, I expect MS to throw everything at the wall this Holiday season, as I think it would possibly be their last chance at a meaningful upset that might turn the tides (in the US and UK). I could definitely see them doing an instant price dop to $299 if Sony goes there in October/ November. Perhaps even as low as $249 for a "temporary promo" around Black Friday.
They'll loose a ton of money around that, for sure, but if they don't turn things around this Holiday season, it's pretty much over (in terms of market domination, not "the XB1 is Doooooomed").
Even with that, If Sony decides to expand their reach and go for $299, I would then see them winning the Holiday season, and perhaps with a good margin too.
But if they decide to play it "safe" and do a half step at $349, I think Sony will likely loose the Holiday by a (relatively) small margin but that'll net them more money otoh.
