There'll be plenty of 3rd party support. The games will be very, very cheap to develop for. As such, many smaller developers will be putting out Revolution games. While we may not get games like Prince of Persia, or something, but Rev owners will play lots of new series and more unique games.
Plus, some games will end up playing better on the Rev too. The controller would be perfect for playing something like Splinter Cell, or RE4 (maybe 5).
