You're not getting much joy when it comes to the PSP Go. Here in the UK we're getting Gran Turismo PSP and three free games. Despite some early speculation that Sony would offer a "goodwill program" to those upgrading to the PSP Go, an SCEA rep has confirmed this plan has been put on hold, "We were evaluating a UMD conversion program, but due to legal and technical reasons we will not be offering the program at this time."
Sorry USA. But like we've said before — if you do buy the PSP Go, Sony won't come and take your old PSP and UMDs off you.
