Learning a third profession at level 80

Nerrisa brings up an interesting idea on the forums that I hadn't considered before-- what if we all got to choose a third profession when we reach level 80? For some, handling two professions is more than enough, but there are also plenty of people who could definitely benefit from a third. And although the professions are paired off pretty well (Alchemy and Herbalism, Leatherworking and Skinning), there are definitely some trios that would work well also-- Enchanting goes great with anything, and Mining, Blacksmithing and Engineering would be a great combo, too, for power players who've reached 80 and are looking for lots more to do.

Of course, Bornakk says no to the idea (actually, as Incgamers points out, he really says there are "no unannounced plans" for it to happen, which is quite a few qualifiers for him), so it's unlikely that we'll have an extra profession slot to face Arthas with. But don't forget that we will have a new profession, Inscription, and if Blizzard adds many more professions, maybe we will need a third slot to keep them all straight. I'd love for my characters to learn more, I'm just not sure if I'd have the diligence to get them all to 375-- I'm having enough trouble with two as it is.
