Here’s another clue that Apple might be launching new Macs at WWDC

Shipping times for Apple’s 15-inch MacBook Pro with Touch Bar have slipped from same day to 3-5 business days in many countries. Deliveries have been conveniently pushed to June 6 or later in the United States, just a day after Apple’s WWDC keynote, indicating refreshed models might be unveiled during the keynote.

Delivery estimates for the 15-inch MacBook Pro models have slipped to June 6 or later in other markets, too, including the United Kingdom, Australia, Canada, France, Germany, Hong Kong, Italy, Netherlands, Singapore and Spain.

Shipping times for the 13-inch MacBook Pro models have not changed, MacRumors reports.

Bloomberg recently reported that Apple could upgrade its Mac notebook lineup at WWDC next month with faster Intel chips and updated internal architecture.

Intel in January unveiled new Kaby Lake processors that could be appropriate for the 13-inch MacBook Pro models. Earlier today at Computex in Taipei, the chip giant announced a new Core X chip brand, including a new Core i9 desktop processor line with up to 18 cores and 36 threads of power.
