They can do both, dude and it's unlikely with development costs being at an alltime high that they can justify exclusively next gen.
I'd imagine that all games from here on out will support current and next gen systems until we reach a point where Sony and MS just stop manufacturing the current gen base models.
Yeah, it's just weird to reboot Splinter Cell this late in the gen, cross gen or not......Rainbow Six made a resurgence, that's good, but that came quite early.....I'm not sure how well a new SC will do now, so late in the gen......I think they should slow down a little, let some of the games cook....
I think Beyond Good and Evil 2 could be a great release right now though, and I hope they have more on that....On some of the other franchises, you don't want to burn them down too fast........Crew 2 and WatchDogs 2 did'nt do as well as they wanted, newer titles there would be too soon........We had so many Farcry games this gen already, AC will AC I guess....Yet I think they should slow down and concentrate on even better quality and perhaps some new IP's for next gen......
No matter what, a new gen is coming, you need to make the investment early to compete.......too many companies just feel they will continue to cash their now-popular titles, but when people grow tired or a franchise gets bad reviews like Fallout or people don't buy, then they go back fiddling papers on their desk......You need to make the investment early and not get complacent that your cash cow will always provide....You need to prepare for the next gen....
As for the OP; I think Ubisoft should remaster the Splinter Cell games, at least 1-3, before they reboot it.......
