Yes, they are. The most significant change is the Moria culture icon, another is the different placement of the copyright information, and the "flavor" text on the Gandalf side is slightly different. Also, the contrast of the 0M1 is a bit lighter than the one of the 1M1.
I presume that the 0M1 was printed before the 1M1, because it only lists one officially-sanctioned tournament in Virginia Beach, whereas 1M1 only mentions "sanctioned tournaments around the world."
I guess, only die-hard collectors will want to have both versions...
