Count me in as a "yes" that all Pros will have at least some SSD storage (perhaps 32GB-64GB for OS X), and that they will make a big push for SSD-only models. They'll keep hard drive for storage, particularly at large capacities. If there is a 250GB-500GB HD-only model, my guess is that it won't carry the Pro name (i.e. it will be limited to the MacBook).
