... based on collector reactions to the Clone Wars animated line since Toy Fair, I don't know how likely it is that Clone Wars will be super successful. At least the figure line.
I think Hasbro's point though is that the animated line is geared directly towards kids and NOT we collectors. Kids are the future collectors and if Hasbro sees a spike in sales from the animated line, they may continue for the sake of garnering a whole new generation of collectors. With 10 years left on the contract they (Hasbro) has to do something to keep it interesting for themselves and consumers.
Let's face it (as I've mentioned before in this thread, IIRC) many of we current collectors either are getting burnt out, don't have the room, don't want to collect another whole line, etc. Hasbro is NOT looking to us to continue the line. I'd venture to guess they really want "fresh blood" or in this case fresh greenbacks infused into the buying of their SW toys. Kids and teens will do that. Adults collectors, not so much.
While I do very much want Hasbro to continue with the realistic line, I can't say that there are too many more movie characters I need/want. Plus, I DO think Hasbro is dipping way down the well for some of these obscure figures/characters.
The animated line should it evolve to include the PT and OT would give Hasbro a chance to release the same good old heroes all over again, but in a new style.
It's a risk to be sure, but depending on the sales of this animated line, they may be willing to take it.
Again though, this is all conjecture from us at this time.
