Grand Theft Auto: Liberty City Stories at E3

We're not sure if this is the official title of the upcoming Sony PSP GTA game, but Clutch wrote:

I was able to check out a few of the booths being built at E3 this afternoon, one of which was that of Rockstar Games. It was pretty simple—basically just a bunch of buses parked inside a chainlink fence—but the important part was what was painted on the buses. You see, each one was dedicated to a different Rockstar project, and, nestled between a Midnight Club bus and a Bully bus (delightful alliteration, might I add), was a bus that was painted totally black but for a bit of text that read, "Grand Theft Auto: Liberty City Stories" directly beneath the PSP logo. Could this be the official title of GTA PSP?

Sounds like it. Let us know if you see anything else interesting Clutch!
