They've already said they expect to be releasing the XGP in 2007, after the GPKiDS is 'out the door', and that most of its design is ready, and the remainder of what is to be done involves selection of an exact SoC. Beyond that aspect I'll have to ask for the OK before saying more, but I've posted quite a few e-mails in the General XGP Discussion subforum that might shine light on a few frequent Q's.
