As you all know Icy Prisms will sometimes give you an epic gem in 3.2. Well, all you need to do is save up your icy prisms and open them when 3.2 hits and hope that the loot will be there. This is more of a theory but it should work.
*edit* Mail them to a bank alt and put them in a guild vault or leave them in the mail and open them in 3.2. If any of you flamers who posted the link for icy prism actually looked at comments you would have noticed that this theory has also been posted there, however I was not aware of this at the time I posted it. Try again flamers.
