It will probably take a while for us to get Killer Frost, if at all. I know we got confirmation from the actress who plays Caitlin Snow that she will become Killer Frost but she didn't state whether or not it would be in another alternate timeline. The Killer Frost we saw in the wormhole was just one of many possible futures. As Wells put it all of time itself is being displayed; meaning all possible timelines. It is possible that she will become a big bad for maybe season 3 or 4, but I find it more likely that a doppelganger of Snow will appear from an alternate timeline and it will be played out for maybe 1-3 episodes or so. That makes me think of how interesting it would be if there were two of them!
