I'm about 70% sure that this will be the schedule.
If you want to bring in a player in GW33 who will definitely have a Double GW soon then your options are limited: Villa, Everton, Palace and Saints
The fixtures for DGW26, DGW27, DGW28(?) and Villa vs Spurs moving to GW29 should all be announced when the March TV fixtures are announced at some point in the next 9 days.
The announcement of the fixtures will likely be made before the GW25 deadline (Friday at 6.30pm)
Here's this season's Blank and Double Gameweek schedule:
🔥DGW24🔥
2 extra fixtures
🔥Double GW25🔥
1 extra fixture
🔥Double GW26🔥
Lots of extra fixtures
❄️Blank GW29❄️
Lots of Blank fixtures
❄️Blank GW33❄️

And there will be some other small Double GWs 🔥
