As nice as the Faamba is, mine's left legs (front and back) are shorter than the right legs, and he leans in that direction unless something is put under his feet to balance him. It's probably just mine, though. I can't see buying another one unless they switch the "accessory" on top to be the shield projector rather than the drum, though.
I'd really like to see an updated Dewback. I like the POTF2 version, but it'd be great to see a totally new version with a Sandtrooper that can sit on it. Make it a Battle Pack, throw in a couple of Sandtroopers and the Escape Pod from the 2004 Ultra Threepio, give the Sandtroopers a couple of those levitating probe droids from the SE, and call it a day.
