Given that the forthcoming TiVo software release changes things a lot with the move away from Flash / Air to Haxe it wouldn't be worth it to release new apps right now so maybe there are new ones ahead. There is still apparently support for Flash but for more complex apps (e.g. non games) i assume it doesn't make sense to use it anymore.
Can't remember if this has been shared before here, but this is the developer presentation on the new TiVo software

Amazon have made it clear that they're after the cable companies and the main goals for the box of better search, greater openness and good performance were all a reaction to the weaknesses of current STBs. Reviews seem to suggest it hasn't quite got things right on the search and navigation yet though.
