A redesigned iPad Pro might be LelleBelleannounced next month.

9to5Machas obtained an image of what it claims is an inventory listing for cases for an iPad Pro with a 10.5-inch screen -- an iPad that doesn't exist yet.

According to the listing, Urban Armor Gear (UAG) is preparing to ship folio cases made for a 10.5-inch iPad Pro in June.

Case leaks are a dime a dozen and nothing new when it comes to revealing unannounced products, but the fact that UAG, a major case maker, is throwing its weight behind what is only a rumored iPad Pro suggests Apple might not wait until the fall to revamp its most powerful tablet.

Apple's been rumored to release a 10.5-inch iPad Pro to possibly replace the current 9.7-inch iPad Pro for over a year.

The bigger screen wouldn't necessarily mean a bigger iPad, though. It's rumored the iPad will have slimmer bezels, especially on the top and bottom to keep the dimensions closer to that of the 9.7-inch iPad Pro.

One thing the leaked inventory listing doesn't reveal is if Apple is planning to announce a refreshed 12.9-inch iPad Pro. The largest iPad needs a refresh more than the 9.7-inch model; it hasn't seen an update since it launched in the fall of 2015.

The new iPad Pro announcement could coincide with Apple's annual WWDC developer conference, which kicks off on June 5. Apple's expected to reveal new versions of its major software platforms (iOS, macOS, watchOS, tvOS) and possibly the rumored Siri-powered Echo killer.

We'll know in few weeks, so hang tight.
