Just seen some stats for 2012 so far, I believe it includes house shows but not dark matches:
With John Cena winning at Saturday's SuperShow in Tucson, he won his 100Th match in 2012. He needed 108 matches for that (4 losses and 4 draws/no contest).
Daniel Bryan has the most matches in 2012 so far with 113 matches (35 wins, 74 losses, 4 draws/no contests).
Impressive statics includes Brodus Clay (78 wins, 1 loss) and Ryback (52 wins, 1 loss).
