I believe it's actually $500/month for just this "Enterprise" subscription, which gives you some level of support and access to a bunch of themes and plugins. Seems like the VIP level is different, and includes 24/7 phone support.

Will be interesting to see how the support actually stacks up. My experience with another popular "enterprise" Wordpress platform was been shockingly subpar (bad enough that we just bailed out and ate the loss since we paid a year up-front).
