It seems that Vita is keeping an average 25k with the new models.

Actually, the WiiU game lineup in Japan is pretty poor, compared to the western lineup. There are a lot more games available for WiiU in the West than Japan. 

No wonder why it´s doing so bad there.

Nice Vita hold in there, next two it should be rising further.
3DS is phenomenal as usual, and terrible for WiiU, but I hope Party U can have some effect on its performance this holiday.

Its amazing how Japan hates Sonic.

Its not hate more like dont really care. 

If SEGA/Sammy didnt have their foots up their rear ends, they would bring back Yuji Naka or hire Prope to develop a new Sonic. I dont think theres any other chance the Japanese are gonna accept him or care again.

No, all they need to do is to add mario in the title then people would start caring XD 

Prope looking at their wiki they mostly developed moblie/ handheld games and will games. Unless thats where you think the franchise should go. 

Woot! My psvita prediction was spot on! I feel so special right now (j/k). Where's my cookie for getting it right?
