Gamezebo has a review up for Twinkle Toes Skating
Imagine: Ice Champions which is the sequel to the earlier ice skating game (like before, originally Japanese, translated for the market) is now released.
(There's also a Imagine Ballet Star game in the Imagine lineup which might have the same kind of gameplay, not sure. The graphics look cute and the price is currently really cheap, so if you have a ballet fan around, might be worth grabbing?)
An upcoming Divas On Ice looks like it may be related to the other DS ice skating franchise, Princess On Ice.
