I'm not saying it justifies a $350 price point (though this is probably going to also be gone in about 6-8 weeks too), but the Wii U is out of the "launch window" phase IMO officially now with Pikmin 3 here and Rayman Legends, Wonderful 101, and Splinter Cell Blacklist also coming out in a matter of weeks.
The system definitely "graduates" from being a launch product now.
