So I was thinking the other day about this...
The Deluxe Figure w/Vehicle line is neat, and they are doing the Yavin Tech w/Sled... Not a bad choice since people are into the set, but what about other "Original Trilogy" based ideas?
I was thinking about this more in the context of the "just off screen" designs rather than things that were actually in the movie, but really either one would be cool I think.
One I'd really dig seeing, from the movie, is the Hoth Speeder/Gun Platform thing from the cut footage... It's just about the size for a Deluxe Figure w/Vehicle format I think, and a Hoth Trooper variation with it would be ideal (or Luke I guess, with maybe a more weathered deco?).
I was also thinking it'd be really neat to see an MLC-3 update though... A modern sculpt of the cool tank design. It's something I still pick up to use with modern figures, actually. I just love the MLC-3 though, as a small gun carriage. It reminds me of a Bren Carrier from World War II or something like it. Rolling along with Fleet Troopers, giving some supressing fire when they need it. A mini-tank.
I could also see Hasbro whip up a Rebel Speederbike with a unique Rebel Scout... Not the McQuarrie design, something a bit more traditional and like the Imperial bike, or a Swoop perhaps. Even a repainted Swoop sculpt they have like the Pirate Speederbike Bane came with? With a cool Rebel Scout figure on there, it could really do well I think as an army builder.
I was thinking also that little "pod" type speeder from Mos Eisley would possibly work as a Deluxe Fig w/Vehicle... Not sure who you'd sneak in with it, but it's OT based, unmade, and maybe could include some kind of Bounty Hunter character?
I just really would like to see the Deluxe line expand from the Clone Wars a bit and look at the Original Trilogy more... the upcoming original designs from Hasbro are neat, and have inspired me a little bit to hope for some expansion of the line.
