On the eastern side, the future looks very bright:
Level 5, wants to release Time Travelers, Fantasy life, Guild 01 this year, also at some point we will see Prof Layton VS Phoenix Wright
Square has Kingdom Hearts and Bravely Default
Capcom has RE:Revelation and Monster Hunter 4
Konami has Metal Gear Solid 3D (tought I wold have like more a re-edition of peace walker) and Beyond the Labirith.
Other than that we have Tekken Prime Edition from Namco, and Extreme Escape Adventure: Good People Die from the 999 creator.
On first party side it's possibly even better with Paper Mario, Luigi's Mansion , Fire Emblem, Kid Icarus, Animal Crossing, possibly Smash Bros at some point.
On western side, on the other hand, I don't see very much going on. Aside from Rayman Origins port I can't name any other interesting game. I think west developers decide which platform they'll support mostly basing on tools and tecnologies they can use. Since 3DS is uncapable of running Unreal Engine 3 and similars they won't spend much time on it. Also, they're too much focused on HD gaming. At best, they'll wait to see how good games like Resident Evil and Metal Gear will perform, than decide if it's worth to spend some resorces on 3DS.
Honstly the only western company who has some potentially interesting imo games is EA with SSX, Burnout and Dead Space.
