Some goalies might have the potential, but may not have much chance of fulfilling it. Having said that, I'm sure that at least one team will take a chance on a keeper in the 1st - it almost always seems to happen. Would most likely be late 1st round by a team with multiple 1st rounders.
I think it's more likely to see several goalies go in the 2nd round with a team's 2nd or 3rd pick in the draft - the top guys like Trevor Cann, Jeremy Smith, Linden Rowatt, Mark Owuya etc.
Don't forget how difficult it is to predict how keepers are going to pan out. Right now it might not look like any of these guys are sure-fire starters in the NHL, perhaps 1B or career Back-ups. In a couple of years they might have progressed immensely to be bluechip no1 keeper prospects (eg Justin Pogge, Thomas Greiss) or equally fall off the scale the other way.
