when is 4.1.2(or later) update expected for the wifi-only Tab 2 7.0 P3113?

Side-question: Can you upgrade directly from ICS 4.0 to JB 4.1.2 or 4.2 since I balked on doing the JB 4.1.1 back in January (in Canada) ? I'd like to know if I will have to go through each version incrementally !

When I set up a co-worker's tab 2, I had to do each upgrade from ICS to Jellybean incrementally. At first I thought there was something wrong with the system, but it was taking a while to do each update.
