Yeahh I don't think so, it'll be like the Vita without the niche games... so basically nothing.

Oooh you got me! lol

But PSP was successful. Sony just somehow completely screwed the Vita.

No thanks.. It would be quite unnecessary if you think about it.. :-/

Xbox can't handle consoles, why go to handhelds?
I'm sorry i don't know why xbox handheld would be necessary.

I doubt they ever will.

First party MS Devi HAVE worked on games for Nintendo handhelds at some point, Diddy Kong Racing DS anyone?
And I remember there was a Halo DS?

10 years ago, yes. Now, no.

There is not a big enough market for dedicated handhelds that there could be three. From my perspective the market is big enough for one manufacturer and thats Nintendo. Sony is struggling aswell and what can Microsoft do at all to make a proper handheld. Sony and MS should concentrate on their Xperias/Nokias gaming functionality.

Definitely no.

Never. There is no need for it.

No, plus in a way it already exists its called a Nokia Windows phone (owned and made by MS).
