Do you see 3DS, PSV and Wii U sales as a sign for concern or excitement for PS4 and X1 sales?

[Pavolink]

Those 3 consoles already launched were not what people wanted or expected. Word of mouth was/is almost zero.
3DS is the only one with possibilities of turning around, but never will reach the highs of the DS. Vita and Wii U on the other hand seems like a rejected product by the market.

X1 and PS4 judging by the "omg fuc**ng amazing pre-orders* pr will start well, but I don't know if being so similar to their respective predecessor will help.
