Apparently, 20th Century Fox will release The Good, The Bad And The Ugly on Blu-Ray, on 29 april in The Netherlands. That's about as much info as there is as of yet. Not even the website mentions any of this. Since it's released by Fox, I assume it will be region locked. See here for the press release. Just scroll down, it's the last entry. Let's keep the fingers crossed for an actual (and above all, decent) release.
