GTA: Chinatown Wars coming to PSP

Rockstar confirmed today that the former DS-exclusive GTA: Chinatown Wars will be coming to Sony’s PSP in the US and Europe later this year. There will be both a UMD version and a digitally downloadable version for the new PSP Go.
Rockstar’s contradictionary press release first states that the game will be “specifically built for PSP”, but then that it will have “upscaled widescreen graphics”. Apparently the PSP version will also feature “enhanced lighting and animation, and all-new story missions.”
We gave the original a 10/10 in our Grand Theft Auto: Chinatown Wars review, so we are optomistic about this port. But it will be interesting to see how Rockstar handles the loss of all of the excellent touchscreen elements and a seperate screen to put the PDA on.
