Okay, I've made the determination that it's an AA battery and not the smaller AAA version. How you say? By looking up pictures on these two sizes of Duracell specific batteries, I've found the that text "Duracell" on the AA battery matches, while the AAA text is smaller and does not go as close to the "negative" side of the battery.
Now since we know that AA batteries are 1.98 inches in height, we can reasonably extrapolate the size of this new tri-droid.
See the pic here for the size. I used the vanishing point tool in Photoshop to do this. It's a rough estimate. I think this toy is about 28-30 tall!

Mind you this is not with the legs fully extended and two of the legs are on a lower plane. Still 28-30 inches is HUGE. I'd be ecstatic if this was a $20 toy. THough I think it's going to be more in the $30-40 range. Price will dictate my buying multiple. I only want up to 3 of them. If they are $20 I'll get three, if $30 I'll get two, if $40+, then it's only one for me.
And yes, I'm a proud graphics and math nerd! (even if slightly inaccurate....lol)
