I'd been thinking about picking up the Saga book to look at the mechanics for awhile now, and with the 4e announcement I grabbed it at B&N this weekend. I've only glanced at the skills chapter but I can give you a bit of an overview (though IDHMBIFOM).
The 5 classes each have a number of trained skills (ranging from 3-6 I think, plus Int bonus) they can choose from their class skill list.
ALL skills, trained & untrained, have skill modifiers equal to 1/2 level (rounded down) plus the relevant Ability Mod (IIRC). If you're trained, you get a flat +5 bonus on top of that.
That's it. No skill points, no skill ranks, no synergy bonuses, nothing. Some skills can still only be used if trained.
Again, I only skimmed the list, but compared to 3.5e, the skill list is shorter. There's only Perception instead of Spot & Listen, Stealth instead of Move Silently & Hide. I remember Climb, Jump & Tumble, along with Ride, plus Pilot. Deception instead of Bluff (which may also incorporate sleight of hand stuff?). Knowledge was still a list that you selected areas from individually.
Hopefully if I've misremembered some particulars someone can quickly correct me. I'm not playing Star Wars at all, and in my group we're playing a primarily IH-game with the AE magic system instead of 3.5e, so I'm basically just mining SW Sage edition for whatever looks better. As always, YMMV.
Thanks.
