That's pretty much the standard at all the races....4-5 days maximum before the actual race is when the DRS zone(s) is/are confirmed. They confirmed the zones for India on the 25th, race is on the 30th. Korea...confirmed 10/12, race 10/16. Suzuka...confirmed 10/6, race 10/9.
Hopefully, after the season's over they're correct the ones that are wrong in a patch...not holding my breath, though. I read on their forum a while back in a post from one of the CM staffers that they didn't expect to be able to do 2 zones per track, like some of the tracks had though. They were looking into a way of doing it, but hadn't been able to get it to work right so far supposedly.
We'll see what happens.
