It was reported that Japan will receive small amout of WiiU's for start. With few-times-already-sold-out-MH3GHD-bundle on Amazon and at stores (as well as standart consoles; prices for them so hiiiiigh on auctions already... (MH bundle priced up to 52,000 yen)
it's safe to say that people don't want to preorder just games w/out consoles in many places (retailers like Yodobashi even not began to take preorders for the system from 6/10 - they're waiting something from N, next step, promo, i dunno; secret lol), and promo campaign not even started in a full force now (tiny ads at many shops, no TVCMs, etc). So a little later everything should stabilize for launch.
Btw, Mario, MH (and Nintendo Land) going to drive system this holiday in Japan. Of course those western games are dead ones here. And "MH3GHD vs. 3rd HD thing in this thread is so funny, lol. Wii U has 0 userbase now, PS3 had millions when 3rd HD released).

Very hapy about Bravely Default. Japanese gamers LOVE IT (4.6/5 rating on Amazon, lots of posts with tears of joy on blogs, such as "true classic FF" la la la. Even without big promo, it started great, sold out in many places a few times (At Amazon, again, it even been priced more than 8K yen, now with new shipment game climbs to #1 again! In a THIRD WEEK. It's really interesting cuz it's new IP and all... Not often something like this happens in Japan with new IPs http://www.amazon.co.jp/gp/bestsellers/videogames/ref=pd_ts_zgc_vg_videogames_more?pf_rd_p=113885689&pf_rd_s=right-5&pf_rd_t=101&pf_rd_i=489986&pf_rd_m=AN1VRQENFRJN5&pf_rd_r=0R3NCJENQASDF0SHZ8PH
