Sinizine: It's kind of hard to gauge if it's been cheaper as it's just been updated and the old package's history seems to be lost.
However, Steam always has Bethesda/ID event sale during Quakecon, so I'd wager if it's going to be cheaper it'll be then, and may include more games.
Yeah, I got the Bethesda / ID pack during the Quakecon event and it included all of these games, plus the Elder Scrolls games, Fallout 3 GOTY, Fallout New Vegas with the three DLCs released until then, and Brink.
I would wait until the next Quakecon, myself. It'll probably include the remaining Fallout New Vegas stuff, RAGE, Skyrim (possibly) and the Brink DLC that got released later.
