Amazon could be set to release their anticipated tablet or a new Kindle as early as September 28. The company sent out invites to select media today, inviting them to attend a press conference scheduled for next Wednesday.

While it's very possible that Amazon could simply be planning a Kindle refresh for the event, most media believe that the online retailer will unveil a 7-inch Android-based tablet, dubbed the Amazon Kindle. Earlier this month Tech Crunch claimed to get some hands-on time with the new tablet (sans photos or videos, unfortunately), saying the device resembled a BlackBerry PlayBook in terms of form factor.

TC further described the device as having a capacitive, full color touchscreen and a price point of $250. The Android software looks nothing like what we have seen thus far as the interface is all Amazon and Kindle. There is no Android Market or any Google app.

The unit was suspected to have a single-core CPU, but this couldn't be confirmed. Expect around 6GB of onboard storage with more available in the cloud and no cameras. A Wi-Fi only model is expected at launch with 3G-enabled products coming a bit later.

The press event potentially solidifies rumors that we could expect the device to launch sometime in September, although it remains to be seen if Amazon can move an estimated five million tablets in the upcoming quarter as speculated by Forrester analyst Sarah Rotman Epps last month.
