You mean between cloth and a separately sculpted jacket piece? I'd say the separately sculpted... I'm not opposed to cloth most of the time though, but I'm having some Leia Collection flashbacks on the thought of a new Ceremonial Luke with cloth jacket... The POTF2 basic's sculpted jacket was nice, it was his ripped sculpt and goofy "lean" that I hated... I would definitely be into a new sculpt Luke Ceremony then.
I don't think I described it the way I meant to. I meant like a sculpted-on jacket, like the old Ceremonial Luke, or the old Bespin Han. I guess they could do soft-goods, but I wasn't impressed with the soft-goods jacket they did before, and don't know that they could do it any better today. Another option, I suppose, would be a flexible-plastic removable jacket, with separate jacket arms, also removable (like the removable Jedi robes on Agen Kolar or whoever it was last year). I don't know how that would look, but it would be nice to have a removable jacket, since there were some photos taken of Hamill wearing just the black shirt underneath. . .
The Han is so-so, yeah... Still, it's a Han they haven't done yet. I think his sleeves are full-length too (ooooo!), but it'd be different.
By God, you're right!

Maybe a nice smirking face sculpt... 
They better do this for a face sculpt:

And this is how 'Scum described the wave, in a report from last October:
Han Solo
This version of the rogue will utilize interchangeable parts not unlike the Dagobah Luke Skywalker figure from the OTC line. He’ll be packed with a headset (so he can tell his farmboy friend to blow that thing so they can go home…), interchangeable hands so the figure can have gloves or bare hands, and a medal (!!!).
Luke Skywalker
He’s just blown up the Death Star and about to live all his dreams. The future is looking bright for Luke, so he throws on his stylish yellow jacket (no doubt to impress that hot brunette he just rescued), and goes to get himself a medal of honour. This version of Ceremony Luke will be a complete resculpt.
Rebel Sentry
Remember that Rebel Soldier on sentry duty? You know, the dude in the crows nest scanning the Falcon as it approaches the Rebel Base? We’ll here he is, and if a totally new sculpt isn’t enough for this army builder, he comes complete with his with his little fort in the sky.
Gold Leader
Whoa. Before you go into the forums and say how much the Gold Leader figure packed in with the Y-Wing bit, read the rest of this description. The figure will most likely be built upon the wicked Dutch Vander body, but with a repainted helmet and a totally new head sculpt.
Death Star Trooper
This figure is going to be slightly retooled, but who can say if that’s going to be just a new head sculpt , a repaint, or a total kit bash.
But I've been thinking about something, and it's really disturbing. What if, by "new Ceremonial Luke and Han," they're not really talking about the end of A New Hope at all, but, instead, this:

"Luke Skywalker with Drag Queen Make-up To-Hide-Post-Car-Wreck-Plastic-Surgery-Scars paint job"
"Han Solo with Disinterested Look Upon Face headsculpt"
Maybe one day, we'll get "Chewbacca with Life Day Robes" and "Leia with Powdered Nose and Horrible Singing Voice Chip" that will make us all long for the CommTECH days.
Okay, maybe not.
But you guys all know you'd buy a Life Day Robes Chewie.
