I actually couldn't tell anything from that picture, Sal. I suppose I should have saved it and then "blown it up," but I didn't as the thoughts in my mind were racing.
This is an awesome "vehicle" addition we're getting, and like you I plan to use it as a droid with its own brain, not requiring a pilot. (Who could see it if you placed another Battle Droid in there anyway?)
However, in all the stir and excitement over the Falcon, an AT-TE, and a fighter, the Homing Spider has really been kind of forgotten.
Thank you for reminding us about it, as this will really be an excellent piece. Like you, I'm buying 4 of them! I cannot wait! This is the best thing that's happened for the Separatists since the Hailfire Droid (which over-shadowed the Geonosian Fighter - which we recently chatted about).
The Separatists really have some cool stuff: now for the Droid Gunship and the Tank Droid!
I think Kashyyyk showed the best light on the Separatist hardware, maybe moreso than Geonosis or Utopau. But then again, I'm going "EU" a little and plan to use a Hailfire on Kashyyyk as well - just because I really dig that vehicle.
