Sounds good. At any rate, I'm looking forward to the GT League events. I bet that all the events listed as getting new rounds will be specifically getting a round at Spa (with some being dry, and some wet), as we can already see from the preview of the new Gr.4 Cup rounds. I'd imagine Spa would be where the additional X2019 Endurance Series round will be, as well, given that a X2019 race on that track was featured in the FIAGTCs.
As for other rounds, I could see Nostalgic 1979 getting a round at Big Willow, and the Real Circuit Tours getting a round at Monza, or perhaps Brands Hatch.
In the next update after this, I could definitely see rounds at Spa coming to the Gr.1 and Gr.3 events in the Endurance League, as well as in the Professional and Amateur Leagues, respectively. Since Spa is also a part of F1, I could see rounds with that track also coming to the AMG Grand Prix, the F1500T-A event, and maybe either of the other two Red Bull events, with the X2014 Jr. and X2014 Standard. With the Jaguar VGT coming next month, I could also see new rounds coming to either of the VGT Trophy events, too, as well as rounds that compliment the newly-added Demio and Aventador SV - namely in the World Hatchback Championship and the Lamborghini Cup. I could also see Electric Circuits being an event returning from GT6, now that the Taycan will be added. (Even if it's only two or three cars that'd be eligible, that didn't seem to be an issue for events like the Supra or Fairlady Z events.) Perhaps even the Premium Sports Lounge could get new rounds, as two of the three road cars in this update would be eligible for it.
It's still a bit odd that the Spec II moniker was picked when this update (which comes right after its retail release) isn't v2.00, but I wouldn't say this completely rules out a jump to v2.00 altogether. I really wanna see those HRE wheels, too, and potentially more suits/helms, given that I recall seeing a Simpson decal in the default library. (And I think Simpson helms were in GT6, too.) Being able to use the PD-made liveries would be great, too, even including those hypebeast brand liveries, or the Michelin-themed NSX Gr.3 from some events.
