According to a recent report by the Wall Street Journal (WSJ), citing unidentified sources, online retail giant Amazon has plans underway to launch an ad-supported version of its Kindle Fire tablet; that too, at a lower cost than the standard $199-priced Kindle Fire.

As per the report, the ad-supported Kindle Fire will probably be unveiled by Amazon at its forthcoming press event, which will be held in Santa Monica, California, on Thursday, September 6.

The cost of the ad-supported Kindle Fire will likely be $30 to $50 lower than the price-tag of the standard Kindle Fire; and it is being speculated that the new version will be launched shortly after its introduction at Amazon's next-week press event.

Going by the details forwarded by the WSJ sources, ads on the new Kindle Fire - which will apparently retain the 7-inch form factor - will be displayed only when the tablet is woken up from sleep.

In addition, the sources also revealed that the ad-supported new Kindle Fire - like most of the other currently-available $200 tablets - will be available only with Wi-Fi connectivity; thus ruling out the option of 3G/4G data.

The WSJ report about Amazon's plans to launch a new Kindle Fire version appears to be quite convincing, especially in the wake of the fact that the online retailer ran out of stock of the original Kindle Fire this Thursday; and said in response to the supply shortage that it had "an exciting roadmap ahead" for the tablet.
