Yea possibly. I'll wait and see:I'll bet my soul this isn't the case, too often PR people get those things wrong and only later correct themselves to 1080/60 and 4k/30. Unless the visuals suffer massively in the end.

Because it’s Gears, you can play solo or with friends in local split-screen or online co-op, all at 4K Ultra HD resolution with stunning HDR at a smooth 60 frames per second on Xbox One X.
This could be just misleading English to be fair. But without having to be a lawyer, I would read this at 4K HDR @ 60fps.
