It would be cool to get some single player details, but honestly I get the impression that the SP is kind of an after thought, only because RO1 was a mainly MP game and it they are portraying RO2 the same way, of course.
This is pure conjecture, but I'd probably say that SP will basically be MP maps with bots, with maybe cutscenes in between. Again, TOTAL guesses.
We'll just have to see when TWI releases more information.
That's my guess too, more so as what we know of the Coop mode, suggest it's the SP campaign, only humans get stacked on one team versus the AI on the other.
So yeah, i figure it's normal MP campaign mode, only you can play it offline now aswell, and it may or may not have cinematics inbetween maps/stages.
I certainly don't expect it to be a whole linear story driven experiance with dedicated maps like from CoD, nor do i mind, because just look how rubbish thouse are.. no thanks, thouse are just as much an afterthought compared to the MP, which is what people really buy thouse gaes for anyway, i'd rather they spend their time on something else, and we get an SP campaign that actually has some replay value because it plays out more like an MP match (all be it with bots), rather than a series of scripted events.
You know, the UT series did that aswell, and they where actually quite fun to play, and had the positive effect that new players would learn the maps, gamemodes and playstyle of the game by beating it, so i really woulden't mind.
