Here is a bit more, from Nintendo of America:
The famed fighting franchise appears for the first time in HD on Wii U this holiday season, and on a portable system for the first time on Nintendo 3DS on Oct. 3. New characters, items and arenas add a freshly reinvigorated look and feel. As classic Nintendo characters interact wirelessly in the game, amiibo will add a different dimension to game play. Super Smash Bros. for Wii U will be available at a suggested retail price of $59.99, while the Nintendo 3DS version will be available at a suggested retail price of $39.99.
