No PT12HD subscription plan?

apologies if this had been discussed elsewhere, but I'm looking at the "subscription" options in the AVID store. I don't see an option to get PT12HD as a monthly subscription. I'm only seeing PT12 as a subscription option which I assume is the "Vanilla" version since a 12 mo subscription is only $300 and the PT12HD "upgrade and annual Upgrade plan" is $600 a year.
