Gamers tend to be stupid, i dont know the reason but some stupid gamers were expecting GT5 to be better and more complete than GT4... and with more cars from the last decade... and can you imagine they were actually expecting GT5 to have all the cars and tracks from previous GT's.
How stupid is that?
Also for for some odd reason they were expecting to be able to race on the redbull hangar road...i really dont understand why...Maybe cause It was demonstrated with 2 LM cars in this official trailer?

..but how can it be? PD never actually promised that.
But hold on a minute...havent they promised new dlc every 2 months?
-PD promises and word have lower value than a used condom.
Having said all that...
With a dozen of trailers, GT HD, GT Prologue, multiple delays, huge budget, 5 years under development, a zillion resources, many official licences (WRC, Nascar,GT500 etc) People had no choice than to expect a lot and/or much more.
Have in mind (as i said above) that we are talking about a AAA 1st party studio game with huge budget and a zillion resources, that was 5 years under development.
It would be a huge achievement if they could actually release it more incomplete than that.
