As of now, I'm currently waiting for some big, popular games like Planescape: Torment, Baulders Gate 1, and Deus Ex GOTY to go on sale as well as the indie Shadow Run: Returns.

What games are you waiting for to go on sale?

EDIT: And how much of a sale do you want for them?

I'd like to see either the ultima games or might and magic games get another sale.

Gamersgate has the D&D anthology on sale right now, which includes Planescape Torment and Baldur's Gate 1. And they're the same as the GOG versions.

The 1st SpellForce. The new one has me hankering for the 1st one. :D

Wizardry 8, every review I see makes me want it more.

I'd like to see Assassin's Creed go below $10. I had a lot of fun with my Steam copy and it would be nice to replace it with a DRM-free one.

I was under the impression that you had to download them all together as a package and not individually? And I do think there were some other differences, like GOG's copies having compatibility work done to them while those are the original retail versions. Correct me if I'm wrong there. ^^

I'm waiting for an Age of Decadence sale, as well as Final Fantasy 8 at 50% or greater. Sir You Are Being Hunted would be great at 66%+ too. :D

Divinity games, aside from Divine and Beyond. I would like to finish my Divinity collection on GOG.com with Divinity 2 and Dragon Commander.

You're wrong there. The publisher simply took the GOG installers, ripped out the references to GOG and used them for Gamersgate. People even found remnants of GOG paths in the installers. They're pretty much the same.

You do have to download the pack as a single package though.

Arx Fatalis. Just because I have a lot of stuff to play still and can wait a bit longer. It's only $5.99 anyway though.
Oh, and Rogue Trooper and The Penumbra Collection. These I'd love to see come down a bit before I purchase them.

Have your read this?

Defender's Quest: Valley of the Forgotten. I played the demo and loved it, but it wasn't in the Steam Winter Sale and the GOG Winter Sale was mostly bundles :(

A few adventure games I want are on sale this very minute, but I am uncomfortable buying more this month at 60%, especially since I already have those exact games on CD already. I'd just need to futz around with DosBox to get them running. [If they had been 75% or higher, I expect my resistance would have crumbled. Old games that I want and don't have on CD already, now those I would have been happy to buy on the 60% sale. ]

There are some adventure and puzzle games on my GoG wishlist that I am looking forward to getting on sale sometime: Fez, Broken Sword 4 & 5, Night of the Rabbit, UnEpic, Lilly Looking Through, Gomo, Septerra Core

I caved and bought a few of the ones I'd been waiting on a sale on this weekend: The SWATs and King's Quests.

Beyond that, I'm not buying anything else for awhile, because the backlog's getting out of control again. I am waiting on a sale on the other HoMMs, though-hopefully a decently big discount. I have 3 here and 5 elsewhere, and while I'm interested in 1/2/4 I don't need another copy of 5 here so much.
