I remember seeing something somewhere about the release date but I can't find it anymore.

First of all, we assume Sion will be farmable in 12 weeks.
26th Feb 2018 was his release.
On 9th April 2018 he was moved to Chromium Pack
And maybe from the week of 21st May 2018 he will be farmable in a location.

Source for Release Cadence's here, key word is "Release Cadence": https://forums.galaxy-of-heroes.starwars.ea.com/discussion/164741/dev-blog-character-release-and-event-cadence-3-30-2018

I was allowing a little extra variance in advance of all the "Where is Visas/Sion why isn't she/he farmable yet" threads
