With just one day left until Apple’s massiveiPhone 5 introductiontomorrow, it’s a mockups day today. This morning already saw us post a few nice dummies and mockups, from theiPhone 5 dummywith high-quality closeups of the handset’scontroversial two-tone designto aconcept videoshowing off its possible features tothis nicely done mockupof a mini iPad in hand.

With some people expecting new colorful iPods at tomorrow’s event, designer Guilherme Schasiepen went about rendering half a dozen stunning mockups of what a fifth-generation iPod touch might look like. The renderings and more food for thought follow right below…

You gotta give it to Guilherme Schasiepen because I’m simply smitten by attention to detail glaringly evident in these renders.

It looks pretty darn thin, doesn’t it?

I love the four-inch Retina display with a 16:9 aspect ratio.

Of course, the smaller 9-pin dock connector gets a showing as well.

Here’s your black model.

I prefer my iOS devices in white

Guilherme’s also done a set of gorgeous renders depicting a 2012 version of the iPod classic, Apple’s music player that started the whole iPod craze a decade ago.

Here’s one of the iPod classic concepts.

We heard whispersthat Apple could tomorrowrefresh the iPod lineupalongside thenext iPhone(even iMacs, perhaps?).

Apple reportedlyhas in store nicely redesigned iPod touches with beefed up internals, tweaked iPod shuffles in eight new colors and an elongated iPod nano, also in eight bright colors and sportingrumored WiFi iCloud connectivity, perhaps for Apple’salleged streaming music service.

And if@chronicis right, the next iPod touch will run a new application processor: an ARM-based S5L8942X rather than an S5L8950X. He also thinks Apple will finally enable the hiddeniOS Panorama modein the Camera app.

What do you think so far?

Is this how the fifth-gen iPod touch should look like?
