The fix didn't make it to the first ServicePack we didn't have sufficient time and resources to implement it. The second ServicePack included only some Validation fixes, that were crucial for our users, and didn't contain any other control fixes of features.
Also, at the time of writing of the previous post it didn't seem feasible that we would have enough time to fit this fix into our schedule, and that's why we couldn't commit on the release date being the next major Q.
However since then we have re-examined the issue and we managed to resolve it, so it would be available in the 2013 Q2 release, which comes out in mid June.
