Hey Shakkai,
I have this one too - got it as a division from a friend last summer and it sulked and sulked...but it has several new growths now that look like yours. Asked him about it, and he says that the spike emerges from the tip of the new growth before it unfurls it's leaves (unlike coel. cristata which makes a separate spike at the base of the bulb). I've been checking mine for signs of a spike every day, but so far haven't seen anything. At least you'll be getting a nice new growth!
