Yeah, if America really was going to be super crazy for Xbox the first one would've been a smash success. I think only a minority REALLY get worked up over "Murica", when you have much of the same software but cheaper and at higher performance then most sensible consumers will go with that unless something about the Xbox is legitimately more appealing.
I can't help but wonder if the lack of BC is a factor too though. Not that it'd have been practical to implement, but in that case you'd have that sort of ecosystem preservation thing going on: you get a new iPhone rather than a hot Android because you're invested in the ecosystem, or vice versa, but outside of XBL/PS+ subscriptions that doesn't exist this time...
... well, mostly. PS4 actually does have the advantage with the cross-platform-when-ported games, and I think the only case of that happening on XB1 that didn't involve a paid upgrade for a last gen title was for Loco Cycle, and that came out with the current gen and I'm not 100% sure I'm remembering right about that being a cross buy game. But at any rate neither are strong ENOUGH to convince people to stay that really want to move, so it was kind of a blank slate.
Honestly I don't think the market for up ports like this is very big.
I mean Tomb Raider has been $5 on PC and very cheap on consoles.
They'll probably turn a small profit, but I don't expect to see a lot of up ports.
I actually expect we'll see more of them in the second half of the generation than the first part similar to last generation, just a few big games that can be easily done or are by publishers who seriously think it's a good idea. Once the generation's further in there'll be value in cashing in on people who missed it the first time and wouldn't mind a collection or a cheap digital re-release.
