Yes and it will only be about 5K. Or maybe we can get the FAMAE version that's coming out. Wouldn't expect that one to be less than around 4K though either.
Right now the two main contenders are the XCR-M and the RFB. I have the RFB. If the XCR-M shot like an AR10 (.5 moa) then I would get one of those as well. But right now accuracy between the two seems similar and the RFB is a heck of a lot more compact. .308 semi auto in a rifle the same length as a Tavor.
The ergonomics of the XCR-M are excellent and better than the RFB. But it's also a lot bigger of a rifle. The main thing with the RFB are the slightly awkward mag changes compared to the XCR-M or the very quick mag changes on the Tavor. It's not bad but it's not military rifle fast, the way the XCR-M is. However the size of the RFB makes it very nice and handy for shooting off hand or taking through the bushes.
