Alrighty, I feel like we're in a good enough place to start talkin' car predictions for the next Series.
Apex Allstars is honestly a specific enough title that the theme is genuinely easy to predict: Track Toys, whether Extreme or not, likely from the 21st Century or the turn of the decade. We know we very well might be getting the Venom 1200 here as a New-to-Forza, it lines up pretty well with the Track Toy category and could honestly fit in either the Playlist or the DLC, assuming we're still gonna be getting those. I'm siding with DLC because it feels more like a legend of speed than a straight-up Track Toy, but again it's pretty much either/or at this point.
Now that we won't be having a community challenge anymore to distract from possible experiments with playlist structure, I'm betting that we'll see another case of the Exclusive Events, since that seemed to be a huge hit with the Suggestions Hub. I don't think this theme is deserving of a 40 Point Car Week extravaganza--so we'll still be getting 20 point cars--but that just means the New-to-Forza cars can afford to be way more specific in their theming.
With that in mind, here's what I predict:
Summer: GT3/GT4 street model--this could be a 2022 Porsche 911 GT3 RS, actually (thanks Justuxful and Fred for clearing up confusion!)
Autumn: Hennessey Shelby GT500 Venom 1200 OR an equivalent American Track Toy--this will depend on whether or not the Venom 1200 is indeed a Playlist car or not
Winter: Maserati MC20--because this is pretty much the last 'real' chance for this car to appear in an update for a while, I suspect. This might also be the season the headline car comes in with, either way.
Spring: Race car, maybe a car ported over from FM2023
The Hard-to-Finds this month, then, might be returning from High Performance or Upgrade Heroes. It's high time for the GT Black Series to come back, for sure, but beyond that, it's a mystery.
There's also the possibility that, if this is going to be a 40 point car Series, they could pair these off with a race car--like, street car for 20 points, race car for 40 points. It just all depends on what they're going for.
As for the DLC... That's up in the air. The Venom 1200 has a purported top speed of 311 miles per hour, which means a possible theme there is Top Speed Legends if it is indeed DLC, to branch off last month's Acceleration theme. We could see the Bugatti Mistral (top speed 261 MPH), Koenigsegg Gemera (~249 MPH), and the SSC Tuatara (295 MPH) here, for all we know.
