This has been the perennial problem with Nintendo consoles (though not so much their handhelds) since arguably the N64: for one reason or the other, usually Nintendo's almost fascistic rules for developing on their systems (especially in cartridge days), devs other than Nintendo struggle to find the necessary return on investment, and so they tend to sag considerably in third-party support.  This is true now more because of paradigm than technology: developing a multiplatform game is not trivial in the best of times, but at least if you're working with Xbox and PlayStation systems you essentially have the same controller and similar technical capabilities, whereas with the Wii and Wii U you'd essentially have to redesign the game's controls at the minimum.

Nintendo is just such a great developer of games, though, that it makes it almost heartbreaking.  Every Nintendo system has some of the best games of their respective generations, and those are almost always published by Nintendo if not outright developed by them.  And Nintendo's approach is so refreshingly original all the time - not with every game, but they always seem to have something new coming down the pike, these days mostly with Mario and Kirby - that it just makes me sad when I accept that a Wii U would gather dust 11 months out of the year, but be my favorite thing in the universe for that twelfth month.  That's how the Wii was, and the Gamecube too.

Anyway, I already suspected I'd get a Wii U eventually - I tend to get Nintendo consoles eventually - but this E3 looks to have given me the reasons I needed to finally decide this was definitely happening someday.

I'm also excited about YWW because it is clearly an attempt at recreating the awesome of Yoshi's Island on the SNES.  I know it's not the first time they've attempted such a thing, but still, I totally feel good about it this time.

And who can't be excited about Mario Maker?  Seriously?

It's true, all the announcements this year were like, why should you buy a new console if you haven't already (and if you have, look what's coming for you!).  The only real peripheral/hardwarish things were Nintendo's little NFC figurines whose name I forget, the ones that are like Skylanders or Disney Infinity.

I'm so entrenched in certain brands at this point (and happily so, I suppose) that it requires a bit of a shake-up for me to deviate.  I generally know I'll want a PlayStation any given generation right now - that's how I can safely justify having a PS4 already, although to be fair inFamous: Second Son and Metal Gear Solid V: Ground Zeroes aren't things I'm SAD to have gotten to play already.  I know I'll want Naughty Dog's output, MGSV proper, and so on...and that generally Sony brings in enough variety (both with domestic stuff and a greater number of Japanese-developed titles relative to Xbox) that I find things to play at any given point.

Conversely, I've never found an exceptionally compelling reason to own an Xbox - I really like the Halo series a lot, but that's the only thing I feel like I'm missing in general.  Gears didn't impress me much - I prefer my cover shooting a little more limber, like Uncharted or Tomb Raider.  And I'm not a frequent online multiplayer gamer, which is definitely Xbox's primary audience now.

Nintendo's always the one that drags me in late, because I can't reliably assume, as I can with a PlayStation, that there'll be things to kill time with between the releases I really want.
