Unleash everything they have over the next couple of years, then launch a better spec'd box alongside PS5, priced similar if not less than PS5, and let third parties do most of the heavy lifting early on, assuming XB can lock up some exclusivity and marketing from them. I would assume this is what they will do if PS5 launches 2019 or 2020, somewhat similar to how the PS4 launch went. I see this leading to another gen similar to this one in terms of sales, with XB struggling to keep up.
If I were XB, I would take the extra time to make sure I've got the entire American military behind me before taking a jab at PS5, so wait until 2021. Get the first party titles out over the next couple of years and hold off PS4 as much as possible. Give enough time and build up their first party, add a new IP or two, and lock up as much third party exclusivity as possible. Make sure that 'XB2' has very solid and steady first party ready to go, strong affordable hardware, some AAA third party marketing, and gamer friendly PR on a level that 360 nor PS4 could touch. This is the general formula I think they need if they are going to try and give PS5 a run for it's money.
The longer PS5 is out before 'XB2', the worse it will most likely be for XB, but I don't see PS5 launching any earlier then a year in advance. If PS strongly feels like XB is going to wait, I can't believe they wouldn't be willing to give PS4 another year of sales, as long as they aren't declining too much, and as long as they can get PS5 out before 'XB2' if they want, which shouldn't be a problem if XB holds off until holiday 2021.
