Available stocks of current-generation, 12.9-inch Apple iPad Pro devices are dwindling across the board — perhaps hinting that a refresh is imminent.

According to the Check Availability tool on Apple’s website, most high-volume Apple retail outlets are completely sold out of certain 12.9-inch iPad Pro models — though there are a few exceptions (in what probably are lower-volume brick-and-mortar stores). The lower-priced 32-gigabyte Wi-Fi and 128-gigabyte LTE models seem to be most affected by the stock shortage. Interestingly enough, nearly every single store will get new stock on May 16, per Apple’s website.

Similarly, Cupertino’s online store seems to be completely out of all 12.9-inch iPad Pro models — regardless of color, storage or connectivity options. Per the website, new orders are expected to be shipped in 2 to 3 weeks (which still puts those orders in the early- to mid-May range). Of course, this doesn’t automatically point to a device refresh on May 16 — but, combined with other rumors, the stock shortage could shed some light on the timing of Apple’s latest iPad release.

The highly anticipated iPad Pro refresh is certainly looming. Previously, the vast majority of rumors suggested that the new iPad Pro devices would be released alongside the new, entry-level 9.7-inch iPad in March or early April. Of course, that didn’t actually happen leaving much of the Apple news ecosystem confused over the conflicting rumors. Others such as DigiTimes, have reported that the iPads would launch in the second half of 2017 (with a June release being the earliest). That rumor is looking more and more likely as time goes on. Others, like Apple blogger John Gruber, are even predicting a fall launch.

Apple is largely expected to unveil two new iPad Pro devices this year: an updated 12.9-inch model, and a mid-size iPad with minimal bezels in a brand new form factor (reportedly, somewhere in the 10.5- to 10.9- inch range). Both devices are expected to run on Apple’s A10X chipset, and both should feature True Tone displays. While we might have a few good guesses, at this point, it’s totally up in the air exactly when these new iPad Pro devices will be unveiled.

Great news for those of you who’ve clung so tightly to your 4th generation iPad. Apple recently instated a policy change in regards to service requests for the now discontinued 4th generation tablet. Specifically, in instances where customers need to have their device serviced or repaired for any serious reason, Apple is now offering them an outright replacement with a considerably newer, more powerful iPad Air 2, according to an internal memo from the company that was obtained by 9to5mac.

“Starting March 30th, iPad 4th generation whole unit repairs may be substituted to iPad Air 2,” the memo reads, in part.

Apple has essentially authorized its retail staff, as well as select Apple-authorized retailers, to start shipping a variety of iPad Air 2 models as replacement units for customers who’re seeking service on their 4th gen models, in cases when stock of the aging, long discontinued iPad 4th gen isn’t available.

Apple’s 4th generation iPad, which was the first to feature the company’s Lightning port for charging and data syncing via USB, was discontinued back in October, 2014, when the company announced the iPad Air 2. However, Cupertino’s policy has typically been to continue offering support and repairs for discontinued products up to five years after their discontinuation at Apple Stores or authorized retailers.

Apple’s internal memo also informs staff to notify customers about the color and storage capacity of their replacement model, since the iPad Air 2 is offered in several colors and storage capacities, including a new Gold color option, and recently introduced 32 GB and 128 GB storage capacities — which replace previously discontinued offerings in 16 GB and 64 GB. That’s pretty good news for iPad 4th gen owners whose devices start acting up, as it entails that the replacement being offered won’t just be more powerful and feature-packed, but also could boast a bit more onboard storage than their iPad 4th gen, depending on availability.

While the iPad Air 2 is now discontinued as well, having been replaced last month with the company’s new budget-friendly $329 iPad, this move is nonetheless great news for those whose bulky-bezeled 4th gen iPads begin showing signs of doom — especially since Apple Stores, and most 3rd party service providers, don’t typically perform repairs to iPad but rather offer the customer a replacement for their faulty model, depending on stock and availability in their region.
