Gurman himself has previously said that there would an iPad lineup refresh at the end of March or beginning of April. More recently, other sources have been more specific, and claimed March 26.
Responding on Twitter/X to one such report, however, Gurman stated only "Not true." He did not elaborate, but also made no comment retracting or altering his previous prediction of an announcement in the coming weeks.
If Apple were to make the announcement at an event on March 26, then typically, invitations would have been sent out around a week beforehand. However, as it did with the M3 MacBook Air, it's likely that whenever it comes, an iPad announcement may be via a press release.
The iPad announcement is expected to include new models of the iPad Pro and the iPad Air, possibly introducing a 12.9-inch model of the latter for the first time. It's also expected that the iPad Pro will gain an OLED screen, and that there may be a redesign for the Magic Keyboard and the Apple Pencil.
