Yep. I found that page, but as you noticed there is no "buy" or even a "pricing" list for those apps. You're right, it's not exactly a "store." It does very little to help me with planning or purchasing easily.
I'm curious if the exit of Karsten means that all of his promises are gone, too. The Store was something he mentioned was coming during SEU14 and would be unique to Solid Edge. Everyone has a list of compatible applications for their bronze, silver, gold, platinum, and diamond partners.
