A bunch of new IPs launched beside a few established franchises would be awesome.
As far as 3rd party games go, I think both the 720 and the PS4 are going to be fine. Major studios are already at work. Both launches will have plenty of content.
I think we need to keep in mind that gamers, as a whole, are never satisfied. Games take a lot of time and money to make, but people become angry if a console is abandoned so developers can work on the next gen. Likewise, if you work to support the current gen, gamers become angry at a "bad launch". Attempting to find a middle ground might result in allegations of both.
I can honestly say that I'm excited about another KillZone, if it's set on earth. Having that as a launch window title would boost the franchise. Another Ratchet & Clank title would be great, but who knows what Insomniac is going to do after Fuse.
