In the German language game magazine Games Trust, Sony Germany product manager Stefan Dettmering said the following:
The game was already delayed once for its release in Japan, so this could all be speculative, but it seems that E3 would be the perfect opportunity to give America what it wants, way-too-realistic driving action.
Already, this is one of the most anticipated games of all time. Sony has spent a buttload of money on the juggernaut, and much of that has gone to marketing: GT5 has three trailers out already, plus a demo.
Do you trust Sony? Will you get GT5 no matter what? Do you know how to read German?
