I'm sorry but much more than half of the HD games are simply not appealing to me, and despite being loved franchises, many will have troubles getting past the 1M mark in each platform.
I know that for someone, it would be awesome to have Dead Space 2 on the Wii, or Battlefield Bad Company, but speaking as a Wii owner and other Nintendo systems, the 3rd party games aren't the most important between all unique and great Nintendo titles.
The 10 most sold game of all time are all Nintendo for a reason.
Nintendo can shit all over this 3rd parties any time they want. They simply don't need them. They need Nintendo.
