New growths and a possible spike on Cymbidium Kusuda Shining x Douglas Dillon

Growth or spike?

     My Cymbidium Kusuda Shining x Douglas Dillon has produced a number of new growth starts, one of which is much rounder than all the others.  Could it be a spike?

This one is definitely a growth start

Slightly larger, but also a new growth

   The last two pictures show what I'm fairly certain are starts of new pseudobulbs.  So what about the top picture: growth or spike?

Cymbidium Kusuda Shining x Douglas Dillon: New pseudobulbs grow, old growths wither

Cymbidium Kusuda Shining x Douglas Dillon

     In early August, I posted about new growths appearing on my cymbidium.  These new pseudobulbs are now 6 inches tall, and growing fast. 

     The cymbidium has 4 "ages" of pseudobulbs currently.  There are the leafless backbulbs, the pseudobulbs that were mature when I purchased the orchid last year, the 2 newly matured growths, and the 2 newest growths from August.  

New cymbidium growth

     While all the newer growths have been adding leaves and getting bigger, the backbulbs have withered into nothing, and the bulbs that were mature last winter have been slowly but continually shedding leaves.  Since the new growths have been vigorous, and the roots seem healthy (if not showing much new growth), I am for now concluding that this must be the normal growth habit for this orchid.

Fifth new growth on cymbidium

     I spotted yet another new growth on my cymbidium while watering.  The young plant now has 3 old pseudobulbs, and 4 new shoots.  Could this newest growth be a flower spike?  The purple tone and the rounded shape seem promising, but there is really no way to tell at this early stage.  At the very least, once the 4 growths develop, this orchid will be able to put on a splendid show of blooms when it is ready.

Also, the small growth in the very middle of the picture remains completely unchanged since November.  I wonder why?

Edit (2/29): turns out I missed one other new growth.  That brings the total of new shoots up to 5, unless there are even more hiding under the media.
