Microsoft always intended to use games as a stepping stone to becoming a broader entertainment play. They were talking about this publicly as far back as the Xbox 1 (the former Xbox 1, now known as the Xbox 1 that isn't the Xbox One) in the 2001 time frame.
I'm fine with that strategy and even encourage it, but as a gamer I'm distraught with other decisions they seem to have made (it is impossible to tell what decisions they've actually made from rumors or misreporting because they are failing on the PR/messaging for specifics of the Xbox One on a spectacularly epic scale currently).
In the long run, the Xbox 360 is kind of the odd duck of the Xbox line in terms of hardware architecture considering the old Xbox 1 was x86 based and basically a closed PC, just like the new Xbox One. Of course, the 360 happened to occur over the time period that Live proved that a full online experience for a console should be considered an essential component. (I just wish they'd stop raising the cost of Live while also increasing the amounts of ads it throws at you (without raising the value to suit), and stop charging for things that are free elsewhere (eg. Netflix, etc), and start using some of the mountains of money they earn from Live to provide dedicated gaming servers, etc).
The Wii U is actually a pretty nice device. I have one. I'll buy pretty much any system Nintendo puts out just to play their first party games, at least until they're forced to go the route that Sega did. But anyway, the remote touchscreen gamepad "second screen" thing is pretty cool I love using it for Hulu, Netflix and Amazon Instant. Being able to redirect the video play to the gamepad device's screen when the TV is otherwise in use is really nice, and it really makes things like searching a breeze compared to using a more traditional remote. Yes, you can achieve the same basic sorts of things with other consoles plus an external device like a tablet via things like SmartGlass, but with the Wii U it Just Works without having to dick around with anything.
