I found out this out there, though I really wonder how serious such an issue can be.

According to a printed report out of Tokyo this morning, Sony is said to be evaluating the possibility of adopting Connectix's PlayStation emulation software 'Virtual Game Station' to Microsoft's XBox. Thereby, making the PlayStation software library available on Microsoft's forthcoming console. This comes on the heels of Sony's announcement yesterday to end their long standing legal dispute with Connectix, and work together on 'advanced emulation programs.' Sony representatives have yet to respond to the report.
