This is disappointing for a lot of reasons, but in no small part because I prefer to buy my apps through the App Store. I like centralized updates, having only the one relationship with Apple and the ability for Apple to kill an app if it proves to contain malware.
It seems Apple and Mac OS developers are headed for a showdown, where the OS locks out non-App Store apps a la iOS or they bend to every theoretical requirement of an app at some point in its future. Possibly of course, Apple is in the process of addressing the underlying OS issues (rootless operation) that prevent a loose sandboxing regime. I would personally like to see developers forced into the App Store, because not all customers are keen on the idea of providing personal and credit card details with every app and for every company.
Apple does need to provide Upgrade pricing and Trials for software immediately. This seems like an obvious and reasonable request especially considering their TV and Music stores already have DRM technology that could be used for trials and the upgrade pricing is done for TV shows and movies.
