Quoted from Whysnow:
The knight is cool but he needs more call outs and heckling to bring in some personality. Awesome toy if Tim can execute on the player insults and more variety of call outs. The knight needs to really feel alive !
Seeing how enthusiastic Tim seemed to be, I think he'll do that (if he's given some time to do so by Stern?). I think you're right that the toy is great and can become more 'complete' by adding a lot of different call outs (not having played it yet, only judging it by videos).
