Kazunori Yamauchi announced earlier today in a tweet that the new patch for Gran Turismo 5 will go live on February 18th, which is Friday next week.
@Kaz_Yamauchi: In the next update. What day 18 February. RT @ driftlover35r: @ Kaz_Yamauchi PP scheme is implemented or when? Have the same advantage in torque power difference, I get the penalty
The patch will include some fixes to the penalty system which has made the last round of GT Academy a disaster with a bunch of people cheating by cutting corners. It’s also expected to enable remote races. Money prizes from races is also expected to go back to normal, which in case of B-Spec means ridiculously low. So make sure you grind the Dream Car Championship as much as possible before this coming Friday.


“Money prizes from races is also expected to go back to normal…” prize money has been boosted? was there an in-game gt5 news post that i missed?
