The 360 and PS3 have given me little faith in Sony/Microsoft. The fact that the rumors are even plausible should be a pretty big indicator of how bad things have gotten. I enjoyed the PS3, but only after it got a big price cut.
The WiiU seems pretty good so far, I've been liking most of what I've been hearing. It's also the only one that's confirmed to be backwards compatible, so right out the gate, it's got something over the other two. If the 3DS is any indicator, Nintendo does at least seem to have some idea of how to handle online shops, even if the interface is annoying.
And I don't see why everyone apparently sees the wiiu tablet like some alien device. It's a 360/PS3 controller with a touchscreen in the middle. Not exactly rocket science.
Honestly, like someone said: Between a wiiu and an upgraded PC, what would you even need a Nextbox/PS4 for?
