I've also, at this point, bought more 5e material than I bought 4e material. Though I played 4e actively for the entire time it was out. However, part of the reason for this is I buy third party products for 5e...and there were not nearly as many third party products for 4e. I did buy more miniatures for 4e, but they were not specifically 4e miniatures they were just miniatures.
I am also having a slightly hard time keeping up with everything coming out for 5e. Because so much of it is optional rules (a lot of the DMG) or story related, and those things require a lot more thought to digest than "Rules option #644 which adds a vaguely slightly new change to an existing class concept some other class concept already had."
