If PS5 aims for 2019, I think the logical thing to for MS to do is aim for 2020 with a more powerful box.
If PS5 is only two years away from Scropio, I'm not sure it will be massive power disparity. If it isn't then maybe MS can wait until 2021.
Scorpio will certainly have the price advantage over PS5.

If you look at my previous post you will see how this works.
Think of hardware manufacturing as generations of tech. For the sake of this exacmple, lets call PS4/XB1 (28nm fabrication) gen 1 and call the PS4pro/Scorpio (14/16nm) gen 2.
The scorpio will cost more than the PS4pro, because its using more expensive gen 2 components than the PS4pro is using. But it will still remain in a similar power band because its still gen 2. Kinda like how the PS4 had around a 50% more powerful GPU than the XB1 even though they are both gen 1 hardware. Though that was due to the design decisions MS made, opting for DDR3 ram and on chip memory which took up space on the die as opposed to PS4 using GDDr5 and no onchip memory which gave them more space to add in a bigger GPU in a similiarly sized die. In this case the scorpio is more powerful not just because theyhave used more of the similar type pf ram but also a more expensive cooling solution to ensure they can run their APU (which again is still very similar) at higher clocks than the PS4pro APU.
Fun fact? The PS4 GPU runs at ~900Mhz. If sony had made the box even bigger, and used a more expensive cooling solution, they could have got the same GPU running at 1.2Ghz and with a resultant power of around 5.8TF in the exact same APU that we have now in the Ps4pro. But there are downsides to this approach. Not every chip that comes off the line would be ableto run at the upper limit of theiir frequency band. But sony would have paid for them anyway. Which means their will be a lot of dropped chips. Which results in the per unit cost of each chip going up. Another reason why the scorpio will be more expensive, though possibly one allevated by waiting a year and alowing 16nm fabrication to become more reliable.
Gen 3 hardware (7nm) will mean another significant jump in pwoer. But this time not just on the GPu side but also on the CPU side. And improvements in memory configuartion and architecture and veen storage solutions taht we don't have in the gen 2 iterations which would amount to an all round way more powerful system.
If MS waits a year to release their XB2 after sony has released their PS5? The issue with that is that its still going to be using gen 3 hardware so it will not be distinguishably more powerful tahn the PS5.
