Who am I? I am an insider. I've been biding my time and have kept quiet (so as to not lose my job!), but I can't take this nonsense anymore. So here's my info, which is necessarily limited in detail (job to keep, remember):
Announcement along with a new Macbook Pro in September. Immediate availability is planned.
- Same form factor. No change in the color or anything else. The tube really was intended to last 10 years. Whether we'll see an update after this one is anyone's guess, though.
- Slightly updated power supply (50 watts more). There is no way that the tube can fit much more than this (e.g., big enough to support arbitrary "2 full-length video cards") without becoming a mini Chernobyl and/or making an unacceptable amount of noise (for Apple, anyway).
- Updated processors providing a minimum of 6 cores and a maximum that is not yet set in stone.
- Updated graphics based on RX-480 variations. Top card is "RX-490" with DDR5X. This is where the extra power is going. Same graphics form-factor (no standard slots). People - especially anyone wanting to game on a 'pro - are likely to be grumpy about the graphics performance (worse than GTX-1080), but compute performance will be 20-50% better than the present variations.
- A bone will be thrown and two flash drive slots will be available.
- Merged TB-3 / USB-3 plus an HDMI port.
This is definitely the type of disappointment I've come to expect.
