I would have to agree but let me play devils advocate...
Looking at the budgets some of these big hitters have you cant really fault the designers / publishers to milk them for all they are worth with each console generation.
Uncharted / Gears / HALO / COD - all have massive budgets, some to challenge the biggest films in hollywood... I am sure I read that the first Modern Warfare (the one that innovated) had a similar budget to Titanic (i cant check this due to the over zealous internet filters at work) checking Wiki it seems thats around $200m.
Bearing that in mind, launching a new IP is somewhat a gamble, especially when doing something completely new where you dont know the target market.
I am not saying dont innovate, instead look at using the other distribution methods available to you... Child Of Eden was a brilliant game, whilst being pyhsically released went on to do exceptionally well when offered as a digital download. Not everyones type of game but its one example of many, for more just look at From Dust, Limbo etc.
Anyway, on a slightly different note cant we all please stop talking about the next gen consoles... yes the WII U will be coming out and yeah, it will (probably) have better graphics that the current gen HD consoles but unless they have good third party studio support (this is Nintendo remember) it will still just be the usual Zelda, Mario, Wario, Luigi games so not that much of a game changer. The lack of information at the moment just compounds my view on this.
The current (HD) consoles still have loads more to offer, the recent XBOX dashboard update has brought full kinect functionality to pretty much the whole thing with more apps to come along. The PS3 is still under-used, even Naughty Dog have said that whilst all processors are doing something they can still optimise their code further so expect good things from The Last Of Us (hopefully 2012 release)
