The ipad 2 hasn't been discontinued has it? The ipad 2 did NOT get a full ios 6 upgrade. ipad 1 has been discontinued & did not receive ios 6 in any form.
ipad 3 has joined ipad 1 in the discontinued bin, I won't be counting on much of anything in terms of upgrades. All Applecare + obliges them to do is to fix or replace ipad 3 if it breaks, it doesn't force Apple to provide software updates.
I am aware that the iPad 2 has not been discontinued. What I meant by stating that the iPad 2 still gets updates is that the iPad 2 is not as advanced as the 3rd gen. iPad but despite that, it still gets updates.
