Games that sell poorly but get great reviews and are highly praised by the fans. Zack & Wiki, and Fire Emblem: Radiant Dawn are the only 2 games for the Wii that come to mind of having prices > $50 in the anywhere close to near future (as in next 2-3 generations)
It is possible that Okami and No More Heroes could join too, but I doubt it. As for future releases, you have to see sales numbers and trends first.
As for PS3, X360 games, I don't follow them close enough to guess.
