The screenshot there betrays one of them. Yep, it's Mystic Quest Legend, the Final Fantasy-lite Squaresoft produced for the SNES back in the early '90s. I suspect this means it's coming to Virtual Console. Exciting? Not really. Mystic Quest wasn't very good.
The second game we didn't know about is Solarobo, a follow-up but not a direct sequel to PSone platformer Tail Concerto. We knew it was coming to Japan, but a Western release, too? That's news to us!
The third game we didn't know about is the absurdly-named Thruspace: High Velocity 3D Puzzle. Google doesn't turn anything up. But the developer is listed as Keys Factory, a Japanese mobile game company, so my money is on some sort of DSiWare puzzler.
