My guess is:
dupreeh December 2019.
gla1ve will be benched in October 2019 after bad performance at the major
They will pull a FaZe and dupreeh will become IGL
There are only 5 players, so there will be a lot of best guessers.
Either Magisk due to being toxic
Or dupreeh due to slump/personal reasons
In November 2019
Xyp9x i believe or magisk
Xyp9x 2020 august
Magisk 2020 july
Device after first major 2020. Retired because he want do something else
Disband after starladder major
I really can't see anyone being cut in 2019, and even with a bad Major, they wouldn't do anything before AFTER the first 2020 Major. And for them to cut anyone, that would require the same player to perform consistently bad in a lot of tournaments.
I think the most pressure is on Magisk and Xyp9x atm. - but both of them regularly pop off. Honestly the chemistry on the team just seems like it's fucking amazing.
And who should do a rat move like Kjaerbye did? If they wanted Gla1ve they would need Dev1ce too. I just don't see it happening. If you want a Danish dream team, you pretty much would pick the entire Astralis lineup.
I think Astralis realize, that if one of them retires or is benched, the whole chemistry of their roster will be destroyed. I'm not sure that if one or two of them (say Magisk and device) leave the team for some reason, others will agree on recruiting two new players. In this case, losing their tier-1-team status is highly expected (inevitable even). And I don't think it's something they'll agree to.
whole team will leave together and make a new org
Device or dupreeh i think
Nearby the end of 2019
+Valde (not as IGL...)
-gla1ve +valde after first major of 2020 in may and 2 majors without win
Xpy6x by early next year but only if they start sucking again
Magisk will go to Mousesport in January 2020 when mouse is top 1-10 Team after performing well at the major.
