Yeah, I think that's mainly due to the fact that the first modern masters sold well above MSRP due to its limited print run, and now WOTC (or Hasbro, it could be Habro) think that it should be a limited product that people will buy anyway because they want it so bad.
As for what we could realistically get, WOTC have shown that they are willing to reprint the fetch lands in standard legal sets, as they did recently in Khans of Tarkir. However, the problem came when they introduced the Battle Lands, which had two basic land types much like the
shock lands did and so gave excellent colour fixing (at least for standard) and the format became four-mana good stuff that ran blue just for
Jace, Vryn's Prodigy. This means we are probably not getting them whilst the
shock lands are still in standard, but it could be a possibility further down the line.
And reprints are on WOTCs mind, as Gavin Verhey said in his article about the guild kits (
link). WOTC do listen, and if enough people want the enemy fetch lands to be reprinted they may just do it
So, personally, I am optimistic about the future of reprints. I don't think that a land kit is the answer, as they will most likely just get bought out by investors and their price will shoot up, but I definitely do think we could see fetch land reprints, whether in a standard-legal product or in a suplemental one.
