As i have now said twice, my opinion, be it right or wrong.
NFS: MW / Splinter Cell: Black List / Tomb Raider have been listed by retailers but then again so was MGS4 for the 360 last week

.
You have to look at it from a business perspective only and ignore your allegiances completely.
Publisher asks dev to make game, dev says ok what platforms do you want it on, publisher looks at console market and previously seen only two HD consoles capable of running the code so answers - PS360.
Now there is a third console, more than capable of running any multi platform PS360 code, so in a great many cases they will make a version for WiiU, all-be it later.
A game like Dishonored for instance which has now price dropped in the UK could be totally reinvigorated sales wise in the second quarter of 2013 for WiiU. If the console has an instal base of over 5 million by March then i see no reason why any publisher would wish to ignore a possible 1 million additional sales to an 'old' PS360 game that is finished it's main development and only needs ported across.
Of course next gen will be different as the developers will have to put in a lot of extra work to make a 'down ported' version of the games to run on WiiU but until those systems are out, WiiU is a very attractive platform for 90% of third party publishers imho.
