All the little eyes around the tuber are much like the ones on a potato. They have potential but sill most likely wind up only coming out of the center depending on the species you have. I have found that some will put up a single leaf such as gigas, titanum, etc. while others will put up multiple like variabilis.It is not unusual for Them to change a little bit in shape and size while dormancy is in affect. When planting I am a big believer in mixing bone meal in the bottom part of a well draining potting mix. Even if you are going to put it into the ground.
