I'm not missing Sebulba in this set. I think he's one character that could stand to be revisited, especially with the current state of figure articulation and how it could be applied to a Dug. And a new pod race Anakin with modern articulation & sculpting would be a fairly welcome, too.
I'm kind of glad this set is all reissues. I can skip this set since I got all of these as basic figures. And considering that there are only a few more pod racers that have yet to be made into figures, I'd rather see a set like this which is ALL reissues and not a mixture of old & new. That kind of lineup leaves the collector feeling used when you have to buy a multi-pack in order to get 1 or 2 new figures.
And on the general subject of pod racers, there are only another three or four that have yet to be made. I think that those can get spaced out over time. As for the pod race vehicles, I agree that it's generally a losing proposition. MAYBE Anakin and Sebulba's pods could get reissued/retooled, but I don't know that there is an overwhelming desire to get them back into rotation in the vehicle line.
