You've switched tack again. Your argument was that the Wii U will do well because of supply issues for the ps4 and the xb1, but now you're arguing it's going to do better because of it's games?
No matter - I'm happy to analyse both scenarios. Boring day at work...
Going with your "supply constraints" argument (and I'm not convinced there will be any, since you can still order both machines for launch day):
I have two consoles set up on my tv. A 360 and a wii. The 360 gets played almost every day. The wii has been turned on about three times in the last three years.
If I hadn't already preordered, and I went out to buy a new ps4 or xb1 in November or December only to find there's none anywhere - and I won't be able to get either until around February, I think it's safe to say I have three options at that point...
a) Just wait - stick with what I have for now, and keep an eye out for a next gen console;
b) Buy a Wii U, and look at the next gen consoles in a few months' time; or
c) Buy a Playstation 3, and look at the next gen consoles in a few months' time.
Despite the fact the U has finally got a couple of decent games, of those three options buying a Wii U is definitely the least attractive.
I'd be torn between sticking with what I have, and keeping an eye out for stock of a decent console, or buying a ps3 - which is slightly cheaper than the U but has a much better catalogue.
In a toss up between ZombiU, MH3, Lego City, Wonderful 101 (so great you included it twice); and Hard Rain, Uncharted, Infamous, LBP, Journey, and Last of Us the ps3 beats the wii U hands down - with the added benefit of it being cheaper for the console, cheaper for the games, and I'd probably get a ps+ subscription and enjoy loads of other games for free.
It's similar for people with a 360. They'd be better off getting a 360 than getting a U.
Ignoring your "supply constraints" argument:
In a toss up between the Wii U or a next gen machine, the three options all have a lack of quality games available in 2013. Each has a small handful. The Wii U certainly has more games - though not many considering how long it's been out. As to whether it has better games - well that's subjective. I can see that one going either way. Clearly you'd argue the Wii U has the better games, and most other people would argue the opposite, but that's largely brand loyalty. (Don't bother telling us about the fantastic games catalogue you now have. Nobody's interested in Mario bums Pikmin Hunter 3.)
The 2013 line-up is pretty even - but 2013 is nearly finished, and we're forward looking people, so lets look to 2014 and beyond. 2014's games lineup for the various consoles isn't going to be as even. It's going to be a succession of quality games for the ps4 and xb1 all year, and a small handful of half-decent games for the Wii U. 2015 onwards, the Wii U will be getting one or two half-decent games a year, and the other consoles will be getting several of them every month.
Conclusion - any attraction the Wii U has (there's not much for most folk) fades into insignificance when you look at it's future.
Either way you look at it, the Wii U is a bad purchase.
It's like you're arguing the merits of HD-DVD over Blu-ray, here.
We all know it's got it's plus points, and films for it are cheap (if you can find them), but it's a dead format. Yes, you could get a player and two dozen films for a fraction of the cost of buying a blu-ray and a handful of films - but any decent films that come out in the next 5-10 years will be on BD and won't be on HD-DVD. It has no future.
And that was despite the HD-DVD actually being a technologically superior machine to the Blu-ray.
The Wii U is in a similar position to HD-DVD - except it's the technologically massively inferior machine...
