I never thought a picture of the loading gate could be so significant
Although it doesn't tell us the main scoring elements, we can take away many things mentioned already:
We are back on good old carpet again (so those offseason drivetrains from two years ago may be good again!).
If there are human players they are unlikely to be scoring or loading anything from the sides of the field, since the gate placement there leaves a relatively small carpeting strip on the sides. So we can assume human players will be behind the driver's station again (or at center field).
A substantial portion near the sides of the field is wide open, meaning any field elements are likely to be near the center or drivers stations.
If the gate is indeed wider (which it appears to be), we may see a dimension change (perhaps teams will be REQUIRED to build robot wider than they are long)? They could have also widened the gates just so the increasingly common wide robots fit easier through them.
The game appears to be on a field, and will likely have robots (pure speculation of course).
