I'm one of those people holding off on upgrading to the E-M1 Mark II, because it currently doesn't have the most important improvements I wanted--namely, vastly improved video C-AF/C-AF-TR. I had just sent the following email to Olympus customer service: "I'm looking to upgrade to the E-M1 Mark II from my E-M1, but all the reviews I've seen says the Mark II's video C-AF and C-AF-TR is disappointing and not much improved from the E-M1. This is a huge problem, because one of the main reasons I want to upgrade the E-M1 is because of the disappointing C-AF-TR in video. With the E-M1, when using video C-AF-TR, the little focus tracking green box often will slip off of the subject and jump onto something in the background instead. I mostly shoot run & gun style videos, with me following the subject as the subject is walking around (at home, out shopping, etc.), and the C-AF-TR is just too unreliable. I have to constantly re-tap the touchscreen to get the little green box to lock onto the subject again, and it often would slip off just a few seconds later. The C-AF isn't much better because it often would not stay focused on the subject. I think Olympus needs to develop much more powerful algorithms to identify and track the subject reliably. And here's my question: Is Olympus going to make improvements on the Mark II's video C-AF and C-AF-TR in an upcoming firmware update? If so, around what time-frame? If the C-AF and C-AF-TR for video is going to be improved, then I'll gladly upgrade to the Mark II. But if not, then I have no reason to upgrade because all the other improvements aren't that important to me (except the fully articulated LCD). "
