New Xbox will be revealed. Ps4, a definite no. I reckon ps4 will be revealed at Tokyo game show,

None. Microsoft still has 40million+ 360 owners to convince to get Kinect.
The PS3 still has so much potential. It's not even at mass market price yet.

I expect an E3 2013 announcement for both.

None. Yep that is how it is.

That might be a reasonable possibility... but definite no, is a bit much.

I think Microsoft will show off its console during the convention. Sony will wow people with a video montage of what their nextgen games will look like in 2014, while revealing a ram expansion for the PS3.

Will Sony EVER stop copying Nintendo?

Improvements, improvements. And I'm sure they started working on that with their Walkmans.
