Thinking about it now, I kind of like Transformers that can "talk" (phrases in the form of electronic sounds, e.g. G2 Optimus Prime, G2 Megatron, Takara's anime-decoed G1 Galvatron, etc.). Electronic speakers and battery compartments can be intrusive and drive the production costs up, but the
Star Wars Force Link toys seem to show a way of doing it that won't drive the cost of the individual figures up (except you'd need to buy the Force Link wrist band). Yeah, having to wear the wrist band is a bit corny, but at least it offers a way to give the characters speech without adding too many additional parts to the individual figure. Would be cool if Hasbro migrated this feature over to Transformers.
