Yeah, it's easy to miss if you don't pop the figure open, or if you have it loose too really, but I know a number of people didn't catch it because they kept stuff on the card... It's good of Hasbro to re-use that sculpt, it really is a great one, but at the same time I think the #41's superior even with the big slit in the back. It's just a hair bit more crisp and sharp looking to my eyes.
The Clone Wars Clone is nothing to blow your nose at. I'd take that sculpt any day of the week if it meant more on the pegs...

Personally, I think Hasbro should be mixing up paint variations by using both the #6 and #41 sculpts, such as with the upcoming Utapau Grunt... Distribute it heavily with both sculpts, make everyone happy... And don't overdo it with paint variants. You have (supposedly) the time, so don't require that all these molds need to be in use for all these different paintjobs at one time... The Tact. Ops Clone would've been much better received if the #41 or #6 sculpts had been shipped along with the TE Gunner sculpt in the blue paintjob in an effort to satiate some demand... Instead I guess the other sculpts were indisposed creating other "clones" at the same time.
Anyway, side rant there, sorry...
