When I was about to order my iPad, I've made a chat with one of the online Apple Store representatives. I asked them whether is there any education discounts on iPad and they've said no. I also asked whether is there going to be in summer, and they didn't say anything. So, must probably there won't be any education discounts soon, but I expect something at the end of summer, or by the time that they are going to release the next revision.

I think that even if there was an educational discount, it wouldn't be too much. Just a few bucks, as a symbolic discount. So, don't expect anything big, neither soon.
 
Your best bet is to wait until you've got a discount coupon for BestBuy or Target (who told me they would carry them next month).
