Apple Watch Sport Space Black-11

Apple will launch new iMacs and a fourth-generation iPad mini this fall, alongside additional Apple Watch color options. That's according to a reliable analyst who has accurately predicted the Cupertino company's plans many times in the past.

Ming-Chi Kuo of KGI Securities is conservative about Apple Watch sales, having forecast second quarter shipments at around 3.9 million, rising to 5.5 million in the current quarter as the supply shortages ease and Apple continues to expand the product's availability to new markets.

However, Kuo anticipates that sales could be boosted somewhat by additional color options coming later this year. He expects Apple to introduce both yellow and rose gold Apple Watch Sport variants; silver and space gray are the only two colors currently available for this model.

Kuo also expects Apple to announce new iMacs this fall to sustain Mac demand. Shipments for last quarter are expected to reach around 5.3 million units, while Kuo predicts that Mac shipments for this quarter will rise to over 5.8 million as sales increase over the "Back to School" period.

With regards to Apple's most successful product lines — iPhone and iPad — Kuo believes big updates are on the way. In addition to an iPhone 6s and iPhone 6s Plus with Force Touch, it's thought Apple will deliver a thinner, lighter iPad mini 4 that is essentially a smaller version of the iPad Air 2.

Kuo doesn't mention any update for the iPad Air, which could lend some credence to a recent report that claimed the device would not get a refresh this fall. However, Kuo does not address the "iPad Pro" that Apple is widely expected to announce this year, either.

iPad sales continue to fall this year, with Kuo anticipating just 8.8 million shipments this quarter — though that could rise to 11 million during the third quarter when new models arrive.

iPhone shipments are also thought to be down from 54.2 million last quarter to 40.1 million this quarter as consumers await this year's refresh.
