It's worth it for Pikmin 3. Unless you don't like Pikmin... in which case honestly save yourself the money until there are more games out. By this time next year though, Nintendo should have their **** together on that front.
You're not missing anything. Unless you're a really big fan of Pikmin or Mario Bros, you should save your money and wait for Smash Bros to come out.
I'm looking forward to getting a Wii U someday, but out of curiosity... how big is your tv? Mine isn't a huge big screen either... I think it's a 32" or a 40"... not entirely sure of it though.You'll probably want to wait a bit to buy the Wii U unless you view any of the current games as must plays (which I can understand for NSMBWU and Pikmin 3). Also, as a warning, I thought ZombiU was a waste of money, and the Lego game was a solid 9/10 in my book.
Also, I recommend buying the deluxe model, it's worth the $50, and Nintendo Land can supply you with a bit of fun.
Unfortunately for me, my TV is too small for the Wii U. :/ About 10% of the image is cut off. 5/5 on each side, so if you don't have a TV on the large end of the spectrum, wait a bit.

Either of those is plenty of room. You shouldn't need to worry. I think they were exaggerating just a little.
