The lack of respect to game devs these days is disgusting.
This is not about the lack of respect. And in no way to game developers.
Thing is game developers are Russian folks that have already completed their part of the job since the patch is live on RU servers for 2 months already. Of course there are some extra things to do specifically for EU servers (like translation and such), but it normally took them 1 month to do it (and I'm pretty sure that texts and all that localization stuff is being prepared together with the Russian one), and now it's already been 2 months and still no announcement.
So it's possible that it will take up to 1 month AFTER the announcement is finally made.
I'm pretty sure the delay is caused by the Cash Shop items giveaway that happened on RU. Every Cash Shop transition takes forever to get from RU to EU (temporary artifacts and Premium system are the latest examples). So if it takes them to decide if they will give free cash shop items (equal to the temporary artifacts, but permanent except for runes) to the new players in 9.0 as long as it took them to bring temporary artifacts and Premium, we won't get the patch for 2-3 more months easily.
