They will either launch at the same time or Microsoft will release their console first imo.
You really think that if Sony is doing a 2020 launch (as it appears from that quote, about crouching to jump high lateron, might indicate) that Microsft will launch a Xbox Two in 2019? The Xbox One X just came out like at the end of 2017.... you think that within 2years of its launch, there will be a replacement for the Xbox One X?
I dont think Xbox does that, it would be stepping on too many toes (those that opted to buy a xbox one x).
