Let me reiterate what Scott said, more or less...
I have some hope for Luke, but man some of these look bad. I may buy Han just to swap a better head onto him, but color me disappointed with this wave, top to bottom.
I'm going to expand a little here now...
-Luke Skywalker... Luke's the most appealing figure revealed because, currently, we don't have a decent DSE Luke and so that's cool. The problem, and they're prototypes so you can't really judge, but the problem is Luke's headsculpt... Man, i hope that changes a lot between now and release day.
-Han Solo Medal Ceremony... Right behind Luke as I'd dig a ceremony Han to go with Luke who looks incredibly queasy... That's a fairly f'd up headsculpt though (again, prototype, things can change), and I'm disappointed to see his holster isn't strapped to his leg. It's a huge plus to the figure if they'd fix that, so I'm hopeful some things change but I'm not counting on it.
-R5-D4... Uhm, I'm fine with the one I have, so I'm kinda meh on this one at all. Unless something's significantly better, then I don't care.
-Cmdr. Gree... Same as above. Nothing wrong with the one I have. Short of this one being vastly improved, why care?
-Utapau Clone... I'll buy one. I have dozens of these guys, one more won't hurt with super duper articulation, but otherwise it's boring to me.
-Imperial Stormtrooper... Ultimate super duper articulated Stormtroopers are cool, but honestly I like the Sandtrooper out now better than this, plus more gear. Not to mention (again, the whole prototype disclaimer applies) the completely ****** looking helmet and rifle. That figure's attrocious in that photo I think, but that's me. I'll pick one up to "fix". Otherwise I'm buying some more Sandtroopers out right now because they're miles superior looking, come with the field pack and pauldron, and rock a cooler gun for sure. Piss on this guy.
Sorry Hasbro, but this wave's an epic fail so far, to use the term the kids love these days.
Maybe things will improve when production images surface. That'sa lot of improvement needed to overcome the bad though. I dunno.
