The latest Apple product is coming this week, CEO Tim Cook confirmed today on X with the words, This week, something is in the AIR. Well, that narrows it down, even if it isnt quite clear whats coming.Apple teases a new product.AppleThe first, and most likely, option is a new MacBook Air. Several commentators have said that the thin and light laptop is due to be updated. Bloombergs Mark Gurman said in his most recent Power On newsletter that it is coming. The M4 MacBook Air unveiling is imminent. In line with the details I reported in the last Power On, Apple is preparing to make a Mac-related announcement as early as this coming week, Im told, he said.That post makes clear that the main update to the current MacBook Air is likely to be a processor change, to put the latest M4 chip into the Air which currently has the M2 chip in one configuration of the 13-inch laptop and M3 chips in the 15-inch and other 13-inch versions.Which means that we may see the M3 chip relegated to just the 13-inch model and M4 everywhere else.Its not expected that there will be design changes to the Air, though the uprating of the processor could see a rethinking of the current range of colors: currently there are four to choose from.Theres something else to bear in mind: Cook didnt actually say he was referring to a MacBook Air. Could it be something else? It could, though that post on X has a graphic which looks like a product thats hinged, such as a laptop. Or maybe an iPad in a keyboard case?Several reports have said theres a new iPad Air on the way, though Gurman is insistent that wont come just yet. The laptop will come first.Thats realistically the only other optionthe much-rumored iPhone 17 Air couldnt possibly arrive before the fall because thats when the rest of the iPhone 17 range will launch and anyway, as youll remember, theres already been a new iPhone, the iPhone 16e in the last few daysit went on sale on Friday, Feb. 28.So, when will we find out?I think the most likely possibility is that Apple will reveal its new product either on Tuesday, Wednesday or Thursday this week.Personally, Id guess it could be as soon as tomorrow: the Mobile World Congress trade show is in full swing in Barcelona and Apple does like to draw attention away from such shows. If not, then Wednesday, I think.Stay tuned.
