Investors are obviously quite optimistic about Apple's (Nasdaq: AAPL) prospects heading into September, sending shares to all-time highs -- and for good reason, too, as the company is widely expected to unveil a slew of new products.

Last month, reports began to surface with some specific dates, saying that Apple was planning on hosting a media event on Sept. 12 to unveil the new iPhone as well as potentially the mythical iPad Mini and new iPod models. Those same rumors pointed to Sept. 21 as the date of official launch, just nine days after the potential unveiling. Well, there are now two more hints that investors and consumers can count on those dates.

MacRumors reports that numerous Apple resellers in Europe have been instructed to clear additional table real estate for iPad displays over the next several weeks, with the deadline being specifically Sept. 12. The most obvious takeaway here is that Apple may be asking resellers to clear way to add the iPad Mini to the displays.

Separately, TechCrunch is on the record saying that Verizon (NYSE: VZ) has instituted a companywide vacation blackout from Sept. 21 through the end of the month, signaling that the carrier thinks it will as many able-bodied employees as it can from its ranks. With the frenzies that Apple product launches have become, iPhone sellers need all the help they can get.

Both reports corroborate the same dates we've been hearing in September, so now that the "when" seems mostly as expected, the biggest question at this point is the "what" -- as in, What does Apple truly have up its sleep next month?

A new iPhone? Without a doubt. A new iPod lineup? Chances are good. An iPad Mini? That would be a game changer. T-minus one month and counting.

Apple is full of game-0changers, which is why it has plenty of growth ahead of it. Grab this new premium report to read more on the Mac maker's prospects. Sign up today, and you'll automatically get free updates.
