Could this be a flower spike?!

My dendrobium orchid that I've had for at least three years appears to be finally producing a flower spike. I can't be sure, it's very tiny, but I have hope. Here's a picture:
This is the first time a bud has appeared at the top of the cane. I understand that orchids of this variety need at least three or four canes before they can bloom because energy is stored in the canes (pseudobulbs).
