Siri sometimes has issues dealing with third-party Bluetooth accessories—especially cars—which can be quite frustrating. And iOS device owners who don’t have Apple’s latest iPhone would surely cheer an announcement about Siri becoming available for older devices and/or the third-generation iPad.

Perhaps among the less likely announcements, though a potentially welcome one, would be a redesign of iOS’s home screen. The Springboard, as Apple calls it, has become increasingly cluttered over the years as it plays host to the 600,000 apps that are now available via the App Store. Folders can be helpful for organizing all your icons, but frankly then you just end up with a surfeit of folders. No doubt there’s a better solution out there; we hope Apple will find it sooner rather than later.

: Nerds everywhere continue to clamor for an update to the now long-neglected Mac Pro line—the latest edition of which is nearly two-years-old. If Apple does unveil new Mac Pros, presumably the most powerful Macs will include Intel’s latest Xeon chips, updated graphics processors, and potentially an SSD option as well. And a new form-factor wouldn’t shock us, either; the Mac Pro’s body hasn’t seen a redesign since … ever.

The Mac Pro may not be the only Mac to see an overhaul. The first half of 2012 has been remarkably barren of updates to Apple’s desktop and laptop lines, contributed to in part by a delay of Intel’s latest generation of chips, code-named Ivy Bridge. So it’s possible—and, if you listen to the rumor mill, likely—that Apple will launch improved versions of its MacBook Pro, MacBook Air, Mac mini, and maybe even iMac lines.
