Are you two going to fight over Casual versus Core now for no apparent reason in a completely unrelated thread? Really?
It doesn't matter if the WiiU is Casual or Core at this point - it has a handful of games that are not available on other platforms and those games are not exactly stellar to begin with - starting next year, the WiiU will be a viable purchase, but not right now... and before people accuse me of fanboyism or anything of the sort, I wouldn't buy a PS4 or an XBox 720 close to launch either, as you never know what kind of issues with the system will pop up or what kind of support it will receive from developers.
Smart move I like that and I will do so.
