Well, to be honest, Ninty took Wii marketing seriously from the start. 7 months later and the Wii U marketing is still dead. They still need to drop that dumb dubstep marketing. It's not............effective.

No games, no need for marketing at the moment. Nintendo must be saving up their markering budget for the relaunch.

I think a single Nintendo land Bundle with a pricecut could work. Not as great as a Wii sport bundle, but well enough.

They did bring the Wii marketing to the Wii U (most of the logic anyways). But i guess you mean advertisiment.

Yes.  They should say "We would like to play.... again!"  or "We would like to play, with U".  An ad campaign emphasising the product is a follow up to the Wii could work very  well.  What it also does is just emphasis fun and the great things you can do with the product in an almost magical way.  Even better are these:

At this point.. doubt it would help without Wii Fit U and Wii Party U... but I don't think it could hurt.. (Hell any kind of marketing period may help.. I mean seriously.. I haven't seen one Wii U add at all... I would not have even known there was a Wii U if I did not accidentally stumble on it at Amazon.. )

 I won't say it is trash, but just... very..........underwhelming........until Pikmin 3 and  Wonderful 101 come out. Besides, Wii U has some good games. ZombiU craps on Call of Resident Evil 6. Monster Hunter 3 Ultimate is a worthy remake, but again, just a remake. The games will come.

I personally love this 3DS commercial:

I don't know about the WiiU, haven't seen any commercials since I don't have cable tv.

 That was  pretty dope. Ninty needs to give females more $$$$$.

3ds wants to say hi... even if it sold double with its current numbers right now for the lifetime (i highly doubt) it wuold be up to 60 million... which would be considered a success already

Almost any advertising woulds be better then there current ones. They are just awful
