More connectivity features would always be nice, especially after Apple came under some criticism for their minimalistic approach in the release of a previous MacBook Air model. The company has hopefully learned a lesson or two from this, and they will give their users enough USB ports with the 2016 MacBook Pro.
Wireless connectivity is a different beast, as nowadays there is a strong push to move everything to the cloud. Which, for most people, makes things like Bluetooth and NFC gimmicks more than anything else.
Apple themselves haven’t been as aggressive as some other companies in pushing for a stronger cloud presence, but they are also obviously moving in that direction little by little. The implications of this for their next release are not yet clear, however.
Last but not least, a few publications have pointed out that Apple may benefit a lot by adding a modern SSD to the machine. More and more laptops ship with SSDs by default, and it’s quickly becoming the norm in the industry, so it only makes sense for Apple to want to join in as well. We wouldn’t be surprised if they even have some more special implementation in mind that they have been preparing to show.
