Looking at the stuff we know about, I'm leaning towards their US software lineups including (but not limited to)...
Wii
- FlingSmash (Artoon) confirmed
- PokePark Wii: Pikachu's Adventure (Creatures Inc.)
- The Legend of Zelda (Nintendo EAD)
- Wii Relax/Vitality (Nintendo EAD)
- XenoBlade (Monolith Soft)
- Zangeki no Reginliev (Sandlot) maybe
Nintendo DS
- Dragon Quest IX: Sentinels of the Starry Skies (Armor Project/Level 5) confirmed
- Friend Connection (Nintendo SPD)
- Inazuma Eleven (Level 5) maybe
- Last Window: Midnight Promise (Cing) maybe
- Pokemon Ranger: Tracks of Light (HAL Laboratory)
- Professor Layton and the Time Machine (Level 5)
WiiWare
- Pokemon Mystery Dungeon: Blazing/Lightning/Stormy Adventure Squad (Chunsoft)
DSiWare
- Card Hero: Speed Battle (Intelligent Systems) maybe
- Game & Watch Series (Nintendo SPD)
- Kappa Road (Brownie Brown) maybe
...I don't think we'll see The Last Story, Kirby Wii, Golden Sun DS or Pokemon Gen 5 in the US until 2011. I also still doubt we actually get Line Attack Heroes... the Grezzo team had an awful track record at Square (Dawn of Mana) and honestly, the game just seems conceptually confusing. Seems to be a glorified puzzle/action game with high production values, really something unlike a retail product NOA would be interested in imo. I really think it's going to get Disaster'd.
