Hopefully that is something more useful than a SD slot and it isn't in place of four TB3 ports.
Well, seeing how these three ports are collectively wider than the two there usually were on the other side, maybe they could have a MagSafe 2/3 port, three Thunderbolt 3/USB-4 on the other side and a 3.5 mm headphone jack? It does look like there's only two TB3s, so I'm guessing that these are still using an M1 or M1X chip with two Thunderbolt 3/USB-4 controllers on the left-hand side ports, and a USB-C 3 controller on the single right-hand side port, much like you have 2+2 on the new mid- and top-tier M1 iMacs.
Also, judging by the keyboard size and the speaker grilles, this seems to be the upcoming 14'' model, which would still be an upgrade over the 2-port M1 13'' models
and the old Intel ones (the latter not on practicality as far as total number of universal Thunderbolt 3/USB-4 ports is concerned, but still equal in terms of speed – old Intel models have their four TB ports shared over a pair of TB buses, whereas the M1s have two separate buses, meaning that all other things, including GPU power, being equal, you should be able to plug in the same number of devices by using dongles and/or splitters – and better by offering more I/O).
I am assuming that an upcoming 16'' model will likely use the M1X or M2 chip and feature all these added/reborn ports, plus three, four or even more TB ports with independent buses, in a true update over the last Intel machines. Remember, Apple now creates their own destiny, and all these machines they've been putting out are aimed squarely at consumers; it's like they're not even trying very hard. Once we get to the “Pro” tier, hopefully they'll go straight for Intel and AMD's jugular and really make them actually Pro, and not just “anodised Space Gray aluminium-Pro”.
