The (little brother) RX100M2 has a filter adapter available from Sony. I can't imagine they would ignore filters on the RX10.
My guess is it's a built in 62mm front thread (not requiring any adapter). If that's not the case, there will be a filter adapter, like the RX100M2.
I can see what looks like a front thread in this video. Expand to 720p to see it more clearly:
