I think Microsoft will release an xbox console every three years.

I think every 4 years concidering what I have seen from them on social media they sounded very much like 4 years would be ideal.

I am all for it by the way I love short cycles DEPENDING on how big the upgrade is, I skipped the PS4 Pro personally but I expect the Scorpio to be a bit larger of a jump especially in amount of memory available.
