R7 won't have all the bells and whistles as my R2. It will have sound and move. It will not have a periscope or arms. Also only 2 doors will open. I'm hoping to add a picaxe board to the holo eye on this droid as well as a special button to amuse the little ones.
(Actually, my wife is writing the blog for R2. In an attempt to be different, as well as make it a bit easier on herself she's doing a video blog. You can subscribe to her channel for updates or check back here.)
