Cranky Kong Confirmed and A Fifth Playable Character For Donkey Kong Country Tropical Freeze?

Last night Cranky Kong was just recently announced and was confirmed as a playable character for the upcoming Donkey Kong Country: Tropical Freeze for the Nintendo 3DS. Now there's supposedly a fifth playable character. During an interview Reggie hinted at the fifth playable character by stating:

"We're not going to reveal a fifth for you."

After being asked if there will be another hidden character. Could he mean that they will reveal it later on or will we have to play it ourselves to find out?
