At Sen Gamer we read that Sony's PSP could be able to connect to Microsoft's Xbox. It was already clear that Sony's new portable can be connected to the Playstation 2 and the PC, but now there are several documents which say that the PSP can also connect to the Xbox. Experts refer to this as smart and remarkable, because it gives independent game developers a chance to give their Xbox games the same connection possibilities as the PS2 version. For example the connection could be used to exchange saved game files.
