I'm a Nintendo fan but I bash criticize every console that sells poorly. When the 3DS was unveiled I said it wouldn't sell and criticized for their mistakes. When the Vita sold horrible I pointed out how bad sales were, put them into perspective and called those out who said sales were alright. I'm doing the same now with the Wii U.
From my experience fans of any console will always defend it no matter how horribly it sells. People saying the Vita (and to some extend the Wii U) just need more time are just kidding themselves - both consoles are selling below Gamecube level. There's only so much a price cut can do (you can actually roughly calculate the effect of a price cut --> sales elasticity) and it's really hard to dig yourself out of a sales hole.
Edit: I used the word "bashing" wrong lol
