Undead Knights demo on PSN was actually full game ?

Tecmo released the demo of their upcoming PSP title Undead Knights on PSN recently.

The gamers who gave it a go were the most lucky chaps. Well those who give it a try noticed that demo in question is in fact the full game.
Tecmo previously told D’toid that the final code for game is yet to be approved, yet somehow it still made it’s way to PSN.

You must be thinking what would cause this mess up ? well the launch of PSp Go and PSN additions. Undead Knights developer have pulled this complete game demo from the service but not before some lucky chaps got their hands on a free PSP game.
