Let's remember that Amnesia did not open on Sundays in 2018, and on Wednesdays in 2019 it was only open peak season and for selected one-offs.
If they stick with the policy of not opening every night, maybe Monday is there choice in 2020?
Circoloco is really too dominant on Mondays to attempt putting on a tech-focused party, so in that respect, moving to Sundays makes sense for Pyramid.
I know some crossover exists with the Solomun and Pyramid crowd, but Pacha (and Solomun himself) are not for a lot of the tech crowd. It's not so much of a head-to-head in my opinion.
I also think the move to Sundays will be logical for more reasons in due course
I think the way these early signs point, it could still mean Cocoon (and maybe a one-off Diynamic takeover, Coxy?) could have the odd Monday, even if it isn't weekly or bi-weekly.
But it's still early days, after all. Lots to be revealed still
