Yeah, new 2012's likely have 231E. Anything after 8/11 should have 231E. No point in upgrading to it unless you're on something super old.
Edit: After further research, it appears that 2011 cars may come with ISTA/P 2.44 or .43, and possibly have 220E software.
Here are the integration levels:
2.46.1 and 2.46.2 are E89-12-03-502.
2.46.0 is E89-12-03-500
2.45.X is E89-11-09-506
2.44.X is E89x-11-09-505
2.43.1 and .2 is E89x-11-09-503
2.43.0 is E89-11-09-501
2.42.X is E89x-11-03-511
I suspect that 231E was introduced around 2.45. I just checked my car and it has 220E.
