@ultraslick,
I was sure YOU would jump in ;)
Whatever, I do believe the game is ready, they are just trying to get the most of it and perhaps to improve some minors aspect.
To me, it is obvious that a late 2010 release date would do good in term of timing but in the same time, they may end up fighting versus angry/disapointed/upsets fans and the expected PGR5 ...
Time to Work !
