I agree, but MS is also moving to subscription-based sales (Office 365, Azure, etc.). It wouldn't surprise me if they stopped selling VS2013 at retail. We all have MSDN Pro subscriptions at work. It is very nice to go out and grab the latest versions of everything as soon as they're released.
My current company don't have MSDN subscription. The VS2008 and VS2010 we currently use are retail copies. It'll create more resistance for my company to move on in the future if Microsoft completely moved to subscription based model without proper adjustment to the price tag.
