I would say that chances are good. Your orchid looks healthy so there's no reason why it can't bloom. When cattleyas are too young or too small to bloom, they don't form sheaths at all. Many cattleyas bloom in the fall and winter, although there are some summer bloomers also. Continue to care for the plant like you've been doing and when the blooming season for that particular hybrid arrives you may very well see buds forming in the sheath. Good luck.
