Chinese toy forum ACToys has finally revealed the toy for the main antagonist of Transformers Dark of the Moon, Shockwave!

Check out these toy images of Shockwave both in robot and vehicle modes. Shockwave transforms into a Cybertronian tank. From what I can see on this images the Shockwave toy is either a Voyager or a Leader class toy. Only time will tell the class size of the figure and its Mech-Tech gimmick as well.
