The launch line up is actually a nice mix of different types of games, though the only thing that I find questionable is having 2 racers at launch from Sony (WipeOut and Modnation Racers).
We have Uncharted which is the showcase title for NGP, it shows the graphical capabilities of the NGP and it is a action adventure game. Smart As does not have enough info, but from what I have seen, it seems to be brain training puzzle game similar to Big Brain Academy, and it uses the touch screen interface as well as motion controls, it's nice there is some sort of puzzle/casual game which seperates itself from the rest of the launch lineup which gives the launch lineup variety. Modnation Racers, I have mentioned before that I think that this game has potential with the creating aspect using the NGP's touchscreen and camera, it is also a good pick up and play game that is suitable for handheld like Mario Kart. As for WipeOut 2048, well a Sony launch isn't great without a WipeOut game for launch. Finally we have Resistance, which won't make it for launch but will be released a 2-4 after launch, the NGP needs a FPS game that can make use of those dual analogs.
As for 3rd parties I am sure they will fill the gaps for game genres at launch with fighting games (SSFIV, MK), sports games (FIFA, PES, Madden, Tiger Woods), and hack and slash games (Dynasty Warriors).
