If the Reserve List stopped existing, would Wizards really reprint all that stuff on the list? I mean, there's plenty of cards not on the reserve list that they don't print anyways, right?
I'd guess that they way they've done it on MTGO would be a model you could look at. Occasional bursts of reprints with things like Masters Editions, but it isn't ever going to just rain dual lands. Though it obviously isn't exactly the same since those sets were the "original printings" for online.
