I dunno how they could build a machine with anything approaching modern hardware that isn't 4K/60 capable. Even my 13" Late 2013 rMBP can do 4K/50.
But I wouldn't be shocked to see two versions: one with 2 TB3 ports, and one with 4. And nothing else. If they do include an HDMI port, will it be the first and only Apple device with HDMI 2.0? Or will they just stick a 1.4 on it and call that good enough?
Anyway, I expect not a lot of cores, only integrated graphics, and soldered RAM. USB-C only is also probably a fair bet. It's really sad that there hasn't been a Mac I actually wanted to buy in so many years now I've lost count.
All Apple has to do to make me happy is release a miniMac with modern 4 core CPU, modern user-replaceable RAM, and two user-replaceable 2.5" SATA slots. I don't need anything fancy, or any changes to the case. Just update existing lines with modern hardware once in a while instead of trying to reinvent the wheel over and over. Still waiting on a simple spec update to the cMP, too.
When the Mac lineup is finally announced, with the Mini included, and those “upgrades” are lackluster with the Mini still strangled by soldered ram, no GPU, 4 core CPU, viciously sealed against any possible user upgrades with third party hardware, we’ll know.. We’ll know that Apple intends to focus on their cash cow iPhone and iPad and push aside their origin in Mac hardware as if it never existed.. If Apple doesn’t capture the world this Fall with state-of-the-art hardware to reassure their loyal customer base they’ll lose many including myself dumping their touted iPhone and iPad and moving to another vendor.. I don’t want to see and disagree with the thinning of devices and losing ports. I still need ports for a myriad of other devices that require a physical connection. WiFi, Bluetooth, and wireless charging do not cut it!!
Single core Atom running at 1GHz, 1GB RAM standard, BTO 2GB, finally dropped the HDD for SSD but only one 64GB option, no USB-C to make us happy but because we complained too much there's only two USB 3 ports as a punishment.
