"Soon" -- and we take "soon" to mean possibly as soon as later today, Wednesday -- Pokemon Go will see a major update in the App Store to add the long-awaited Apple ARKit feature. 

Originally previewed at the company's Worldwide Developer Conference (WWDC) in June, ARKit means that when you turn on the game's augmented reality (AR) mode, Pokemon won't just appear to be vaguely floating above the ground -- they'll seem to actually be standing on real-world surfaces. You'll be able to walk right up close enough to touch one. (But you can't, silly. They're not real.)
