I believe the layout of the seating bowl will be nearly identical to Little Caesars, and also very similar to Rogers Place. That's not surprising since all 3 buildings are designed by HOK.
Spoilers for big images...
When comparing the new development permit application to the 2021 design, the biggest difference is the new Event Level will be about 4.5m lower, which likely means the full lower bowl will be below street level. You will enter the building onto the main concourse and you will be at the top of the lower bowl.
In the 2021 design, you would have been about 2/3 of the way up the lower bowl on the concourse. When you entered the lower bowl from the concourse, there would have been about 15 rows in front of you to the ice and another 10 rows behind, with a Club level mezzanine at the top of the bowl.
In the new design (based on the excavation plan), you will likely be at the top of the bowl and there will be a club section one level down. Both Detroit and Edmonton have this same layout.
I suspect everything above the lower bowl level will be the same as the 2021 design (which is very similar to Little Caesars). The 2021 design had a "balcony" level above the upper bowl that would have likely been similar to the Gondola seats in Detroit (overhanging the upper bowl like a press box).
