You mentioned StarCraft 2. Have you actually played it? It would be unbearably slow with a tablet. A touchscreen is a poor replacement for a mouse, and that doesn't even get into the keyboard aspect. This reminds me of when Day9 did a Funday Monday where the requirement was no keyboard, one person actually used a wacom tablet. Made for a funny video, but it is a pretty awful control solution.
Also, do you expect the entire game to be played on the controller screen or will you just have interface there?
These kind of threads always seem to be working under the assumption that the keyboard isn't an important control device in PC gaming. Sure you could play something slow and not really competitive like Anno or Sim City with just a mouse, but playing a game like starcraft without touching the keyboard is crazy. Also a mouse has a lot of inputs in addition to pointing. My mouse has 10 (granted 3 of them aren't really used for gaming). That alone comes close to controllers, then add in the 109 keys on my keyboard, of course with alt/ctrl/etc you've got hundreds more.
As for MMOs, there are a lot of reasons besides controls that they are more popular on PCs. Programs like Vent/Mumble, Fraps, interface mods, easy to tab out and check something online, keyboard is pretty integral for communication (you don't want to walk into Ironforge and hear 500 people talking at once on your headset). Console players tend to move onto the next big thing rather than playing a game for years and years, and there are hardware generations. This kind of kills the chances of MMOs. Eve online came out over eight and a half years ago, yet it hit a new peak in users this year. How many games from 2003 are still played by anyone much less growing on consoles?
Actually an MMO specifically designed for consoles probably wouldn't be that tough (in terms of controls), but playing WoW (or any PC MMO) on a tablet sounds pretty bad. There are often too many things you have to do in tandem. What if you're a healer. On a tablet I guess you would have to choose the person who needs a heal and then choose the spell. Of course this whole time you would be staring at the tablet and not looking at what is happening in the game. Compare that to a mouse where I can bind different spells to different buttons and click to heal, all while having every bit of information on the main screen. Playing on a tablet would mean both you and the person you are trying to heal are more likely to die. You'd really need to have the whole game playing on the tablet screen for it to even be feasible (same for RTS). Keep in mind I am looking at this from a raiding/PVP perspective. Of course you could easily grind with any control interface.
Will the WiiU be better than controllers for RTS and MMO's? Of course, but that is because controllers are garbage for those genres. I have a feeling you were saying the same thing about the wii remote.
