If there's anybody OT who wasn't the big 3 but is deserving of some kind of cameo, it'd be Lando. I'm sure that's why they haven't mentioned him, so we wouldn't feel ripped off if he's only in it for one scene - so now we'll be happy if he's in it at all.

I still think it could've been neat to have had Wedge as a general. Not a big role, but similar to General Rieekan in ESB. If only Lawson were up for it... unless he expressed disinterest only to throw off the media? *fingers crossed*

My only other choice for a cameo would then have to be Malakili ;)
