So. Who wants to bet that sony will cram this thing into the NGP?

Edit: It appears that spellcheck has caused me to forget how to spell "special". Can someone fix the title? :\
Double edit: I can post links now. I fixed them in this post.

If you are talking about the 3D, then I don't think Sony will be able to pull it off without getting some angry consumers.

it will probably be next console gen though and i rally dont care what the screen is made of

It hasn't stopped them before.
(playstation 3: "Five hundred and ninety nine US dollars")

which was a rip

Exactly.
Well, Third post. I'll fix the links now.

yes now we can click them

On the plus side, maybe now we can send the 3d pictures we take on the 3ds to phones.
But this does make me slightly sad. 3d without glasses was the 3ds's big hook. Now, in the near future, EVERYTHING can have 3d.
Nintendo might of lost the main reason to buy a 3ds with this development to the average consumer. :\

The DSI could do that.................. not really 3d though

More devices taking advantage of the parrallax barrier? Sounds interesting...
