I'm interested in this, in the same way I'm always interested in new hardware. It's cool to see what new innovations can be done, and what it will mean for gaming.
That said, I currently have no plans to dive into the next gen thus far. It took me a few years to get a PS3/360, so I know I can wait(unless they do something I've just got to have). My backlog is so HUGE right now, I can play games for the next 5 years, and never get thru them all. Normally, by the time a new console starts hitting it's stride with quality titles, the system is redesigned along with a price drop, or improvements of some kind are made, so I'm looking to dive in then.
I'm very curious to see what path Sony and Microsoft take, as they have both been able to see the WiiU not really turn the world on it's ear with their tablet controller idea, but I wonder if either of them will still copy the idea and introduce something similar.
I think for any of the big 3 to succeed, they will need to come up with a radical change in the way they do business, and appeal to the ever changing current gaming market. Sony seems to be doing really well with their "Plus" program, so I would think they will take that to another level in the future and expand it in some way.
I would say that Nintendo has already lost this battle. I know it's early for them, and you can never count Nintendo out, but they are very "Unbendable" in the way they opperate, and I see the WiiU being another N64/Gamecube. Successful for the Nintendo in regards to 1st party titles, but a huge failure for everyone else involved. They are loosing money on every system currently produced(which is really something Nintendo has never done before), so a price drop just isnt an option, and I think Sony and Microsoft will price their new systems very well to compete in this current market place. We should see some good battles in the upcoming years ahead, so lets get some popcorn and enjoy the show, it should be a good one
