The hardware is likely there to achieve 4k, its the lack of 4k content on iTunes that can compete with Netflix or Amazon streaming services that is likely preventing Apple from saying that the Apple TV supports 4k at this time.
My guess is that sometime in the next 8 months Apple will announce streaming support for 4k through iTunes and that the current Apple TV now has that functionality. HDMI 2.0 is only really necessary if you're trying to watch sports or play games, neither of which are going to be possible on any streaming box.
Though HDCP may be an issue. Are rights holders going to like high quality 4K content being carried over a non-HDCP 2.2 link? (Though presumably HDCP 2.2 could potentially be added in a firmware/software update?)
