If they innovate, their core players will like them, but they'll get bad sales. If they stay mainstream, the core players will get bored, but they will have good sales.
They'd have to mess up pretty bad to not have me buy it. Like charging $550+. I like the rumors of what it is, a console/handheld hybrid.
The game developers need to work closer with the console manufacturers so we don't see happen again what we saw when the Playstation 4 came out, and it was the most powerful console by far, but the game developers struggled (and some still do) to make the most of the new power they had available, and so a lot of the Playstation 4 games are only slightly better than the Playstation 3 versions.
It's almost as if the developers were hitting a wall of diminishing returns...
