There is a real problem about that and nobody has the answer yet it seems...
They are throwing to trash the massive innovation that allowed them to sell millions last gen, plus re-using the name that is associated with it.
If there is no Wiimote in the WiiU, then games won't be developed with the motion control in mind.
If the idea is that people already have a Wiimote... Than i'm confused. Does that mean the WiiU is an add-on for the Wii ? If i need to have a Wii first to enjoy it ?
This is probably why they kept the Wii name.
This isn't Gamecube => Wii where it was "neat I get to use the GCN controller for some stuff."
This is an expansion on the Wii brand, including functionality with all previous wii controllers (Wiimote, Wiimote+, Wii Balance Board, CC, CCPro, etc..) but expanding it with more powerful hardware and a new U pad.
I think people will be able to wrap their heads around buying a Wiimote for their Wii U, but real confusion (for more casual gamers) would be buying a Wiimote for the new Nintendo Glorbax.
Also, no dev is going to lose money over assuming you have a wiimote, or know what one is. The Wii Mote itself as an icon is more popular than a lot of gaming franchises at this point.
