And (OK this is conjecture) the delay in DLC may well be due to them cooking up something very nice indeed, perhaps that will stop some of the complainers that x car and x track out of thousands isn't included. I'm impatient for new DLC too but sometimes perspective is an important thing. I remember feeling short-changed by GT3, then GT4 seemed like the answer to my dreams. Funny thing is that GT3 was still the best driving game around by a long way, it's just that GT2 had set the bar too high in terms of content. Seeing a trend here?
That trend isn't much to go by since we don't know whether Gran Turismo 6 will arrive before or after Playstation 4. However, I agree with the larger perspective beyond the DLC.
