the ask is what ppl are looking to sell at with a limit order, the bid is what they are looking to buy with a limit order.
As far as future prediction on pps, it could do either way. If it goes to 1's, im looking to load up. if it goes to 4, I am planning on mostly holding. after 4, i see it as a game changer for this particular stock. when/if that happens, imo the pps will change FAST.
