This is the droid you are looking for this X-Wing-mas!
Randomly saw this new interactive toy from Hasbro @ Target last night. It can be controlled via an Android/iOS app over a Bluetooth connection (requires 4 Eneloops which are not included). Target is having 20% off toys atm (thanks Trent86) and this stacks with 10% off on eBay using CAUZ10 to bring the price down to under $100. Great deal considering it's meant to be $99USD RRP from Walmart even though it's listed for $136.99USD. It's $129.95 delivered @ Premium Collectibles, $149.99 @ Toys R Us & $178 @ Zing.
Unfortunately it's considerably bigger than Sphero's BB-8. Although if it was in the same scale then R2-D2 would be quite small as BB-8 is already tiny.
Hands on review and also a video.
Other good deals after 10% off CAUZ10 code:
Star Wars R2-D2 Interactive Robotic Droid $71.28 (this is a big one without app control)
Star Wars Millennium Falcon Radio Control Flying Drone $71.28
Star Wars AT-AT U-Command With Remote Control $92.88
Star Wars Monopoly $24.84 C&C
Transformers Generations Combiner Wars Superion Collection Pack $85.68 (I'd buy this in a heartbeat if the paint job wasn't so fail!)
Transformers Generations Combiner Wars Menasor Collection Pack $143.28
PS Don't forget CashRewards!
Dammit. This is a good price. I bought it for 130ish in store on Tuesday.
