Character Options, the creators of the RoboSapien toy, are working on radio controlled Daleks(and an rc Davros). They are also planning to release a Sonic Screwdriver toy that looks like the one on the new series.
Personally, I’d like a replica that includes a high power led flashlight, a green laser pointer and a decently accurate sonic screwdriver noise.
EDIT: More, via google, at this catalog page: DOCTOR WHO ELECTRONIC SONIC SCREWDRIVER An authentic replica of the Doctor’s trusty Sonic Device. Activate in “closed” or “open” mode. Pressing the button on the “slide” control activates the LED and SFX. Remove the hilt cap of the Screwdriver to write secret messages in Dalek/Gallifreyan codes. Use the UV Emitter to reveal hidden coded messages from your friends… and enemies. Codebook included. (01635) (CAUT: 4) Screwdriver SRP: £9.99
