I foresee there being a download code or something similar for a free game (of Nintendo's picking) to get people to connect their Wii online. It worked quite well for the 3DS.
HDMI cord would be a surprise to me.
I don't see them packing in the Pro Controller... though I'd trade off a packed-in Wii Remote for one any day.
In fact, I'd *love* to see Nintendo offer a mail-in program for folks to mail in their old Wii Remotes for a Wii Remote Plus.
I'm thinking Wii Remote + $10 gets you a Wii Remote Plus. Wii Remote + Motion Plus attachment gets you a free Wii Remote Plus.
Too much to ask, I'm sure.
Not that it matters much, I wouldn't send in my old Wii Remotes. Though it might be funny to send in my Wii TV remote and see what I get back.
