Rumor Mill: Sony to announce PSP2 January 27th?

Sony is sending out invitations to an event on January 27th for what they are calling a “business overview and strategy meeting”. Some websites in the industry are speculating though that this may be a platform to  officially announce the PSP2. Not much else to report here so I'll just list some of what we know about the PSP2.

Just the facts:

1. Publishers in the US and UK have admitted to receiving development kits and test units for the PSP2.

2. Early leaked pictures of the unit show two analog sticks with a slide form factor reminiscent of the PSP Go, though we know this has been changed due to issues with overheating. 

Rumors:

1. The unit will have a touch panel on the back for special controls.

2. The PSP 2 "‘is as powerful as the PlayStation 3" according to some of the publishers developing titles for it.
