Among the familiar IFA blitz, BlackBerry on Tuesday sent out invites for an event of its own on Wednesday, Sept. 24.

“See the Bigger Picture,” the company teases. The hint no doubt relates to BlackBerry’s elusive Passport, which has been officially unveiled but hasn’t been given a proper announcement.

BlackBerry is planning to hold simultaneous events in markets where its brand is strongest: Toronto, London and Dubai. The event is invite-only, so we’ll all just have to sit back and observe the Passport spectacle from the safety of our computers.

The “bigger picture” BlackBerry is referring to is the company’s 4.5-inch square Passport, which we saw the full spec sheet for late last month. If you haven’t been keeping up, the device is expected to sport a 4.5-inch 1440 x 1440 display, a 2.2GHz quad-core Snapdragon 800 processor, 3GB of RAM, 32GB of expandable storage, 3450 mAh battery and a 13-megapixel camera with OIS. Not bad, not bad.

Of course, the Passport might be a very niche device due to its strange form factor. And with devices from Samsung, Apple, Motorola and more coming out this fall, the Passport has some tough competition. We’ll see what the big deal is on Sept. 24.
