The latest title update for Skyrim, version 1.7, will be released tomorrow on Xbox 360 worldwide and on PS3 in America. At least, that's what Bethesda "expects." A European PS3 release will follow next week. The 1.7 patch implements a number of bug fixes, including "general memory and stability optimizations," and, for Xbox, fixes French, German, Italian, and Spanish dragon shouts.
There's no news yet on the PS3's Dawnguard DLC, which has been delayed until Bethesda can get it running at a satisfactory level.
