Playstation phone... a little bit late if you ask me, because Microsoft has come out with their Xbox Live capable HTC HD7. But this Playstation phone seems a little bit promising, as it runs on Android 3.0 and bundled with Playstation Marketplace (I don't know its trademark name) for users to buy and download games.
The phone is likely to be announced in Paris on the 9th of December 2010. It is reported that Sony has been giving out pamphlets giving a hint of a Playstation + phone. We can just hope that the lower 1GHz compared to 1.5GHz HD7 will not take any toll in gaming experience.
The slide version also gives a hint that the phone is not going to be thin. After all, there are rooms for fat phones, as the owner's wallet should have already been thinned in order to pay for the phone.
BTW, I don't think that Facebook phone will ever see the light.
