The Wii has missed out on plenty of big name multiplatform titles but it makes up for it due to the exclusives and Tiger Woods, Pro Evo and Guitar Hero being considerably better on the Wii platform.
Now the U is guaranteed third party multiplatform titles (for publishers that have any sense) at the end of this year/beginning of next year, will be guaranteed third party multiplatform titles next gen (thanks to Nintendo ditching the TEV Unit in favour of a GPU using programable shaders) and, unless Sony and Microsoft 'borrow' the touchscreen idea, will have superior versions of some of the third party multiplatform titles - Tiger Woods, FIFA, Pro Evo, Alien Colonial Marines, Resident Evil 6, Fallout 4, any RTS game and any game that uses an inventory/map waypoints/puzzle solving.
I really wasn't keen on the touchscreen controller when I first heard about it but the idea has grown on me now that I've thought of the advantages compared to a bog standard controller. And if there's a game where a touchscreen controller isn't necessary then it can double as a traditional controller anyway. It gives developers and designers more options, and that's a good thing imo.
I'm still hoping for haptic technology myself but it wasn't present in v4-4.2 of the dev kits and, despite the 3DS not having 3D screens until the
very las minute, I can't see it happening at this late stage. Shame because it would be very cool indeed.
