GT5 Prologue demo; new cars unlocked this week
As new cars, like the Lexus IS F, are announced at the show they will be simultaneously unlocked in the GT5 Prologue demo.
So, answering the much lauded forum question "how do I unlock cars in the GT5 Prologue demo?" is an easy task - patience is the key, my friends.
Keep an eye on the new content in the GT-TV and News options. Even if you don't speak or read Japanese visit anything that is new and then check the showroom whilst the show is underway - you'll get a nice surprise or two as the week progresses.
