In an earlier post, I had mentioned "crazy Gold Making exploits" were also being heavily utilized (other than Remote AH bots) since the 4.0.1 patch but didn't provide any examples.

Well, here they are. These exploits have been working since the 4.0.1 initial patch, but they probably won't be working after today (there will be a lot of hot fixes I'm assuming).

#1 Argent Tournament Pets & Infinite Champion Seals

The Champion's Purse from the Argent Tournament can also be looted for infinite Champion Seals in the same manner as the Unlimited Justice Points exploit. It is currently being exploited heavily to purchase and sell Argent Pets for 700-2000G a piece (post cross-faction to make more gold). You just open the bag, grab the Seals only, leave the gold alone, reset the bag contents (several methods as mentioned previously), and loot the Champion Seals again.

#2 Karazhan Exalted Rings & Infinite Void Crystals

Those special Quest rings you can get outside of the Kara instance can now be disenchanted into Void Crystals. Just D/E the ring, talk to her again and tell her you "lost your ring" and she'll give you a new one. You can also create a macro to talk to the NPC, D/E the ring, talk to her again.

Previously those special Kara rings could not be disenchanted or sold. But, I think it was a mistake since Blizzard made a change so that PVP gear could be sold or disenchanted now (I'm assuming it's an intended change.) I'm not sure if the earlier rings (ie, Friendly, Honored, etc) can be disenchanted as well however.

#3 PvP Gear - New Intended Changes?

It appears that all unused PVP gear can now (finally) be disenchanted or sold. So if you just want to make gold, or you're discarding older PVP gear, you no longer have to destroy the items and can now make some profit from them. From what I can tell by disenchanting results, you'll be making roughly 1G for every 1 Honor Point you spend. But, it's all server dependent (ie, D/E mat prices).
