They did twice with Disco. Granted, the first time was with the third season, which was 2020, a year of a lot of unknowns, so I give them a pass there. The other time, the final season, which was juggling the strikes and having to rewrite the ending of the finale, so possibly excusable. Though in both cases it did get frustrating where we kept having the cast and producers/writers pumping the seasons as "great stuff" and "it'll be worth the wait." How about stop telling us it's worth the wait and tell us how long we're waiting?
But, here with SNW, there's no excuse for the way they're going. We know the season is complete, hell they're halfway through filming the fourth season. And now they've announced a screening at a film festival. There is absolutely no reason to withhold a premiere date at this point. And before anyone suggests it, no the merger isn't to blame here. The merger hasn't prevented Paramount+ from releasing other shows, greenlighting shows or renewing shows. It hasn't prevented them from announcing the premiere dates of other shows streaming this year, and as we see with S4, it's not standing in the way of production of any shows. It's a complete non-factor in this matter.
