I saw in the recent Q and A that Hasbro gave this info regarding the "classic" lineup for 2008:
"For 2008, we are going to take the classic total down by about one wave. So from the current 60 figures this year, expect around 53 figures or so. Episodes III-VI will each have waves along with a The Force Unleashed wave and a couple other surprises in there."
That seems to slightly contradict the earlier report (from the Forcecast/Dan Curto) that following Wave 1 we would have an Episode 2 wave, a Jabba's/Cantina wave, a Death Star Wave, and an Endor Wave (although everything aside from the AOTC wave could probably be made to fit). That would make (with the Force Unleashed wave) 5 waves before the Clone Wars line takes over (as well as the "couple surprises" they mentioned) - along with their total of 50-or-so figures. I don't see us having 10 figure waves (with the five waves they have), so something else must be contributing to that total - unless that includes Clone Wars as well, but that's not how I understood it.
