I would wager pretty solid money that they don't film the prologue. If it's ever shown, I think it will be in pieces and flashbacks lasting a few seconds, and not shown until long after the Two Rivers gang is on their journey with Moiraine, if then. I think relevant background info will be parceled out in dialogue from Moiraine or other Aes Sedai.
I hope they cut the prologue too. But depending on how soon they start doing the dreams the boys have of Ishamael, they could potentially have him around that table.
