Personally, no, I'm not nostalgic for the old couch co-op. Now, let me first say that I do enjoy couch co-op, I've loved playing halo, resident evil, dynasty warriors, mortal kombat, gears of war, goldeneye etc with my buddies in the same room, HOWEVER, few games have been as fun as playing stuff like the battlefield series online, with an even larger group of friends.
I also disagree with the sentiment that games have become more generic. Gaming has grown significantly, so of course there will be more of those samey games, but as a percentage of what's released, it hasn't really changed much. It used to be that there was a lot of samey WW2 games released, now it's iraq war games. I assume in the future there will be a lot of near future games too.
Again, I also disagree that there's a lack of new IP's. There are plenty, and yes, there is also a lot of sequels. For good reason though, people want to revisit these worlds they've come to know and love, and have new experiences in them.
As for specific new IP's, we've had a bunch that have come out recently, or will come out in the near future:
CD Projekt Red is starting production on a new Cyberpunk RPG. Bioware is starting production on a new IP. Square recently released Sleeping Dogs. Capcom recently released Dragons Dogma and plan to release Remember Me. Mistalker is pumping out new IP's every few years with stuff like Blue Dragon, Lost Odyssey, The Last Story. Platinum Games pumped out Vanquished, Madworld and Bayonetta. ID released RAGE. Nintendo with Xenoblade Chronicles and Pandoras Tower (not sure if they own the IP's or their respective deveopers do though). EA with stuff like Shadows of the Damned.
Now, let's look at the indy's and kickstarter stuff. Lone Survivor, FTL, Project Eternity, etc. There is seriously a wealth of new IP's and stuff out there. Also Dishonored, it's awesome.
