So this week we've seen on rumors the statement that Olympus will have future updates for the EM1 and it will be the best video camera in the Oly lineup. If Oly doesn't physically update the EM1 in fall or early winter that would leave almost a year with no change in its video capabilities without a software update for the current EM1. Remember the rumor when one of the EM1 testers said that he saw an EM1 with 4k in the menu system? At $1200 us or below, I would certainly jump at the current EM1 if it had 4K. And I think this would be a huge PR boost for Oly and it would probably make the current owners feel pretty good to get such a performance boast for no big dollars. The next six months should be an exciting time for m43 users. If I go Panasonic I will have to buy at least two more lenses. If I go Oly then I could get the 12-40. 4K video just has too many benefits to me as a photographer not to want it in my next camera. Would 4K in the current EM1 (even only 30 fps/100 mb) make a difference in what you would buy next?
