Pokemon Rumble U has the distinction of being the first Wii U game to make use of the GamePad's NFC feature. As with the Skylanders "Portal of Power," this lets you import characters and store data using collectible figurines, and a new trailer for Pokemon shows Pikachu making the trek from the real world to virtual one.
As previously reported, the figurines aren't required for Pokemon Rumble U as they are with Skylanders. They'll cost $3.99 apiece at GameStop stores, and will be sold in sealed capsules so you never know who you get until you open it up. Eight figures will be sold in all, allowing you to change move sets and store data on them.
