3.2 patch is bringing some changes. Some minor, some not so much. One of the major ones that's a good thing is they're making it so that the standard heroic level dungeons are going to be dropping the same badges that Ulduar is, so you can easily farm up some of the tier 8 gear. They're also adding a new 5, 10, 25 man dungeon for the Argent Tournament. Other than that you'll have to read the patch notes for the class changes. It's still in the PTR right now, so some other things may or may not change.
