According to this Korean site and a posting at the game park holdings on wikipedia.com, GamePark has filed bankruptcy As of March 8, 2007.
[s]I'm not 100% sure if Gamepark and GamePark Holdings are too different entities or what... or if one is bankrupt and the other isn't?????[/s]
but the most consistent detail in the chatter is that the XGP and it's lesser counterparts, seem destined to never see production.

Update
Gamepark holdings (the makers of the GP2X) are not bankrupt.
Gamepark (the ones who were going to make the 'comercial gaming' XGP) are bankrupt.
