I agree, Apple are in business to sell Apple products, simples.
Currently on the UK Apple Store Website;
Out of 22 Sport Watch combinations, 6 (27%) are showing as Sold Out, 2 (9%) showing 4-6 Weeks Delivery. So 36% of the Sport Watch range are now unavailable.
Out of 26 Apple Watch combinations, 8 (31%) are showing as Sold Out, 2 (8%) showing 4-6 weeks delivery. So 39% of the Apple Watch range are now unavailable.
By comparison, the iPhone 6s, 6 & SE are all available even though it is fairly certain a new iPhone is about to be launched in September. Time will tell if this is Apple manipulating supply or the early signs that a New Apple Watch is imminent....
