The Colussus' Lost Arms

Did anyone notice that in the first picture that ever showed the colussus, the colussus is shown with a pair of arms?

It's this pic,

you can see it in it's normal size on the website, I had trouble linking it.



Just thought it's an interesting find

 

I can't find that picture.

 

it's picture number 10 in the last/first page of the screenshot section in www.starcraft2.com.

It's the one where about 4 colussus destroy a terran base.

 

Ahhh I see it now

 

I'm not seeing any arms. I see little spikey things sticking out of it's body, but the Colossus still has those.
