Not sure I understand the strategy here, was under the impression that Dropbox wanted to move further into the enterprise (read:lucrative) space which would favor a constant, subtle, and functional "boring" scheme.

This seems like a tear in the opposite direction and I'm not sure which target user/market it was designed to appeal to. Maybe it's just a refresh to try and stay top-of-mind in the face of competition from Google, Microsoft, and Box.
