I collected this Clone Trooper and the EPII Phase I Clone Captain from my local retailer on 19 Jan 2012.
Essentially, this 442nd Siege Battalion Clone Trooper is a straight repaint using the standard EPIII Clone Trooper base figure. Even the accessories are exactly derived from the standard set that comes with every other recently released Clone Trooper. However, this is still an awesome figure. I particularly like the green-color camouflaged pattern that comes with this figure. Took it out of the box today and snapped a few quick pictures with my Canon IXUS-1oo IS Digital Camera.
Here are two of the pictures I took:
