I figured I'd give an update. So even though mine was just bought last month (new) it had the old software loaded on it.
So after a few days of driving around town I can tell you that the manual tranny feel from a stop to 15mph is gone, and the car doesn't roll back on steep grade streets when the light changes or I leave from a complete stop. I hope that helps.
If I were a gambling man I'd say that it appears as if my car sat on the lot for a while (old leaves under the hood in cracks gave it away) the dealer didn't use initiative to check cars for software versions and reflash the 2012 cars. I can understand their point of view because most people probably wouldn't care and accept the odd behavior in the car.
