Atsumete! Kirby (literally "Gather! Kirby") is coming out on July 7 in Japan, according to a recent issue of Coro Coro Comics.
The hook of the HAL Laboratory-developed game is that you use the stylus to control up to 10 little Kirbys.
So far, there hasn't been any mention of an overseas release of Atsumete! Kirby.
Kirby's a pretty major series for Nintendo - has there ever been a Kirby title released overseas that didn't get a US release?I found one: Kirby's Toy Box (http://en.wikipedia.org/wiki/Kirby%27s_Toy_Box) but, that was probably only because it was on Satellaview.
