Ok, I haven't read all the threads through, but was the "core classic character" Bespin Luke? Or are we waiting on one more announcement??
I don't remember the exact slide text, but wasn't the 2-pack and core character announcement slide just a general what lies ahead for the year, not necessarily at SDCC, granted it's the place to pull out all of the stops, but we'll have more announcements after SDCC as well. The description was a much requested core character, and at least what I've seen on here, Bespin Luke is neither the more requested Luke and Luke himself isn't the most requested character.
I know some are dissappointed with only 2 figures talked of just yet for SDCC preview, but last year, technically, only 5 things were shown new at SDCC, Jabba, Jabba's throne (which I consider a package with Jabba), Salacious Pack, Bib and Leia, so as far as quantity there wasn't a ton of new things last year even, but the WOW factor was there with the Jabba piece. Based on their overall offering of licenses and products, I think Sideshow is expanding it's base a bit from Star Wars and Marvel as core properties, which will upset some people and delight others. I'm happy with what's going on, I have pieces I want to see them do soon, as much to make sure they do make before the line is lost/dies as just being impatient to get them, but I'm enjoying each piece that comes along as they come along, I've been impressed with their entire body of work and I'm enjoy what is and not getting to caught up in what could be.
