Ok, so while I'm still not convinced this isn't all a massive load of wank, because that NX controller has left me forever jaded on this kind of stuff, assuming this stuff is true...
Slim: makes sense, and I'm expecting it to be as cheap as possible. This is going to be the main driving force behind world wide sales as we switch over from early adopters to bargain hunting average consumers and cheap but cool gift hungry parents. The 3 months sales build up is to ensure there's more than enough for this Christmas and a big price cut.
Neo: I'm still expecting this year, and for them to throw as many bells and whistles at it as possible to make it as quite and cool as possible, as well as have as many premium features as they can fit into its big heavy frame. I'm expecting it to release writhin a month of the slim, maybe at the same time, with the later start in production simply because this is a product for far fewer and much smaller markets.
Trinity/PSP3: still not buying a third handheld. A Vita 3000 model though, maybe with built in R2/L2 buttons and HDMI out for remote play/streaming and PS1 games, that I can see. Throw MicroSD storage in there too and that'd be my dream handheld.
