The battle between Sony's PlayStation 4 and Microsoft's Xbox One is already heating up nicely and we don't even have proper release dates for either of them yet! One area that it appeared that Sony's new machine may have the edge was support for the next standard in HD – Ultra HD. With Sony confirming that the PS4 will indeed support 4K Ultra HD for video only (no gaming!), all eyes were on Microsoft during its big Xbox One reveal, only for 4K to be conspicuous by its absence.
