I purchased the Dragonborn DLC last tuesday when it was released, and will purchase heartfire today when I get home, and Dawnguard next Tuesday when it releases. My question is this : Is there likely to be (or has there been an anouncement) of a patch before Dawnguard, or does 1.8 support all (currently known) DLC? I plan on doing a fresh install of skyrim, followed by the patch, followed by downloading the DLC. If, however; there is to be another patch before Dawnguard, I will just wait until then to begin. Otherwise, I will start tonight. Thanks and I hope I was clear enough in describing my question!

Only Bethesda knows, but you can start the game and if (most unlikely) a new patch comes out, you can keep your save, install the new patch
and you are good to go. You have not to worry about it.... . Play your game and have FUN !!!!!
