This happened while we were down for a couple of days, so most have probably seen it, but LEGO announced the Minecraft set at LEGO World.

I'm not a Minecraft guy, so as a set I'm not all that interested (though it looks like all those Minecraft images I've seen online, so I'd call it a success). As a parts pack it's pretty great - all basic bricks/plates and especially 1x1 tiles in good standard colors. I'll wait to see a piece count to know if this is cost effective as a brick-pack.
Also, I don't think we've ever seen printing on the edge of a plate before, which is interesting. I could imagine the little 1x1x2 figure as the basis for a new standard scale of building. It's at just about the same scale as the microfigs included in the various board games.
