Likelyhood of growing from pseudobulb

[reverseboB]

Last fall I repotted a Mtdm Pacific Paragon "Honey Butter" and in the process the oldest pseudobulb fell off. It was rootless but otherwise appears to be healthy. So I potted it up and it has been 9 months with no real change. I keep it watered regularly and in a sunny window. So I am looking for someone else's thoughts. Will it grow or am I on a fool's errand?
