I'd sell now. If you are shelving it, you will most likely miss out on when a particular item is "hot" and after the initial flux of new professions, it will taper off, and you could easily miss out on riding the wave. Sell now, maybe slowly to maximize profits, and bank the gold.

Too bad you don't earn "interest" in the bank, that might actually be an incentive for people to come back! Even if it was low, single digit % rates, and only gained a bit, it'd be enough to make me hord gold instead of items...
