Serious question - can you even record 4K 4:4:4 video on an SD card? Same with RAW? I didn’t think the transfer rates were fast enough on SD cards. I thought that was only achievable on a CFast or SSD card? Also most new cameras come with USB cables to transfer files if needed.
Personally it seems like SD cards are somewhat niche if you factor in the entire MacBook Pro consumer base. Plenty of customers buying the MBP don’t have a use for an SD card slot, and using universal connectors that can handle high throughput and charging makes the most sense for every customer. Not everyone can use an SD slot, but everyone can use a USB port. Getting a USB card reader is not that expensive and they’re pretty small and portable too. I just throw one in my laptop bag.
Ethernet cable is too big of port to fit on a slim design chassis. So it’ll never happen. Especially since the new macs are likely going to have WiFi6 and Apple is all about wireless whenever possible. For the small % of people that actually need to plug in, they can just buy a dongle.
USB-A port may also be too big to fit in the chassis. It’s hard to know without seeing the new design, but usb-c allows for very slim designs.
HDMI is desperately needed, but that port is also too big as well. They could maybe compromise and do a mini-HDMI port which would work well. Of course people would complain they can’t just use their cables they have - but I just think the full size port may be too big for the slim chassis.
Really USB-C just makes the most sense. It’s super small, reversible, allows the highest throughput, can be used for charging, and can handle video, audio, and anything else you may need. Of course I’d personally love to see all the ports mentioned here, but realistically I don’t think Apple will do this if they want to achieve a slim, sleek chassis. I’d love to be wrong though.
