Maybe, down the line, but at launch no. I fully expect Rockstar to turn their nose up at the Wii U and focus on the Xbox 360, PlayStation 3 and PC instead.
It's easy to write it off as anti-Nintendo conspiracy nonsense, but this is just how Rockstar behaves with releases. They follow a predictable pattern of releasing games on platforms that guaranty the highest profit margins. They take into account dev time (reworking engines, optimisation, QA, manufacturing, distribution, etc), and shape releases accordingly.
Or, long and short of it, if it won't make them a bazillion dollars they just don't give a fuck. See Red Dead Redemption on PC. Doesn't matter that it's based off the GTA IV engine. It doesn't matter how well GTA IV PC did, or how many people ask about a Red Dead port. They just don't care because they see the 360 and PS3 as the big money makers. Which they are.
For Nintendo's platforms in the past, there hasn't been enough demand or, in their eyes, a market to support big releases. Who cares if Nintendo fans want San Andreas? It will make tenfold the money it would make on the GCN released on the PS2, and even Xbox. This is where that market is, moreso than the GCN, so why bother?
They'll have a similar attitude to the Wii U. It's a new system, so right off the bat the potential market will be much, much smaller than the 360 and PS3. It's a Nintendo system, so they'll be wary of the audience. They'll take the conservative approach and not bother with a port as there's too many maybes, and the 360, PS3 and PC versions will do more than enough to cover the dev costs.
Maybe down the track when (if) the Wii U has a proven sizeable installbase of customers who buy these kinds of games, Rockstar will release a port of the game. Until then, and unless Nintendo throws some money their way, I don't really see it happening.
One thing to remember with the Wii U and GTA is that Nintendo isn't competing with a whole new generation of systems. This isn't like a couple of systems launching, each battling out with exclusives and deals to outsell the other. GTA V will release on the 360 and PS3, and they already have a massive audience. Fact of the matter is even if the Wii U had GTA V at launch, a vast majority of gamers will still just buy it for the 360 and PS3. That's the system they already own. That's the system they know. That's where their LIVE/PSN accounts are tied to their achievements/trophies. That's where their friends are found.
And that's why the Wii U needs exclusive, new games to draw in new gamers. Proving to the Xbox/PlayStation crowd that the Wii U has all the same games means nothing when those people already own those systems.
