Design question - how to future proof for 2024 iPad when designing presentations for 2022 iPad Pro

Hi. Hope this is an appropriate question for the forum. This is more of a design question than an Illustrator question, but as most people here are designers and deal with problems like this all the time, including in Illustrator, I'm hoping you might have solutions or suggestions.

I'm a commercial photographer. I'm creating a portfolio presentation, (actually using Keynote), for in-person portfolio shows with clients, to be shown on my 2022 iPad Pro, 12.9".

I'm going to spend a significant amount of time on the design of the presentation, having the photographs show as full-screen as possible for maximum impact.

Here's the issue.

Apple will be releasing the M3 iPad in the spring of 2024, with an OLED screen, which I'll want to use when they're released. Of course we don't know the dimensions of the 2024 iPads, though there's a good chance will be different, (critically different in height and width ratios when it comes to design), so hoping for suggestions on what strategies, as a designer, you might make to future proof your design for when Apple changes the screen size and proportions of the 2024 iPads when they're released?

Thanks!
