Don't count on it. If you search this forum you'll see that Samsung has no interested in standing by this line of TV's. I think at this point we know that none of the HDMI ports actually support the bandwidth necessary for full HDMI 2.1 support. As far as eARC goes, considering that they've been promising and delaying it for a year now it can be safe to assume to assume that the either can't due some technical limitation they're refusing to devulge, or they won't because they don't want to spend the resources and have deemed the negative impact on their customers is satisfactory. Either way, don't hold your breath.
