While I appreciate the positive outlook, I'm not entirely in the same frame of mind.
When I see PD saying that said DLC will be availible, it makes me worry because of all the delays we already recieve. What's to happen in the future when we get a GT5 without aftermarket add-ons or damage, then PD settles our stomachs with claims of DLC, only to end up providing DLC on the same slacker schedule we've dealt with over the last few years.
Fact is, I have no reason to believe PD's tendancy to delay and run behind schedule will change regarding their ability to provide DLC.
Basically, it leaves me worried that GT5 will not be the complete game it should be and the DLC needed to complete the game will not be availible until some time in '09.
(that's assuming GT5 gets out before June '08... If GT5 is later than that, I wouldn't expect DLC until late '09 if we were all lucky).
