Probably going to be skipping this gen of consoles

Moving onto PC gaming mostly. Tired of buying these shitty consoles and then only actually enjoying 1-2 games that are made for them.
The Wii, in particular, was probably the worst money I spent on a system (at least, for me). The system just didn't have any third-party support, and I've had enough platformers (Mario) for a lifetime.
And, I guarantee if a new Nintendo console is coming out, a new-gen Xbox and Playstation will be around the corner as well. So that means I'd have to buy the (PS4?) to get my equal share of the third-party market.
I just can't see Sony letting Nintendo get ahead of them in terms of raw power in the system; Sony won't give up the only edge it has in the current market with the power of the PS3.
So, once the Nintendo console is released, Sony and Microsoft will shortly release their new systems, then third-party support will drop (again) just like with the gamecube and Wii, and I'll be back to buying every damn system on the market, with the Nintendo one rotting unused on my shelf.
Unless Nintendo can make a ridiculous performance jump with this system, I just can't see it worthy of buying.
