The PS3 does my Netflix duty, plays Blu-Rays, lets my son play Need for Speed: The Run, downloads demos for the whole family, plays my Child of Eden and Heavy Rain in beautiful high def, and most recently needed an upgrade because I had filled up 59 and 3/4 gigs out of the stock 60. So one 320gb hard drive and 9 hours later, i'm right back in business with the one console that dominates most of my gaming time.
That being said, the Wii is currently burning up some Mario Party 9 and Twilight Princess like it's going out of style. The 360 Elite is the upstairs console to play things I would rather not have my son exposed to just yet, like Catherine and Otomedius Excellent. Whenever a mature title needs to be bought, it's probably going to be a 360 game in my house, and the controller just feels so good anyway...
Wife has a 3ds and is loving it with the street pass feature causing her to keep that sucker on hibernate in her purse all the time. She likes the built in adventure game, earning coins and puzzle pieces, and throwing down on some Harvest Moon 3d. I got myself a copy of the Kid Icarus: Uprising for $30 at Target, and after waiting for 20 years I don't give a damn what score Game Informer feels like giving it ( a 7, by the way ), I'm going to enjoy the hell out of it.
Lastly, I've got a PSP. I don't need a Vita. That is all.
