For example, two of the FCC filings come from a company called Ailen LLC. Assuming that isn't a typo, then the name Ailen could be a reference to a word in a language native to Chile. It means Little Coal, and it could be an indication that someone at Amazon has a sense of humor.
Ailen LLC has 2 FCC filings to their credit, one of which is described as a remote control while the other looks to be the media streaming device. Based on the FCC label, the streamer is going to be a small box with a 4" by 4" footprint (I measured based on the pixels). It has a model number of CL1130, and it was tested for Wifi and Bluetooth.
Assuming I have the dimensions correct, we're looking at a device that will be more than just a media streamer. It might have card slots or additional ports (USB, network, sound, etc). At the very least I expect this to be a much more interesting device than the dongle I had been expecting.
And as for the other filing, I don't know what to expect. It's described as a remote control, and it was tested for Bluetooth. We know that the label is going to go in the battery compartment, so I am guessing that the remote control really will be a remote control - unless it is actually a gaming controller along the lines of the Wiimote, which is not out of the question.
I don't think anyone, not even my source for the other 2 filings, has noticed that the wireless gaming controller which showed up in Brazil has also shown up on the FCC website (or at least the 5 digit model numbers matched, which is so improbable as to not be a coincidence). According to the FCC filing, this device was tested for Bluetooth and has a battery compartment.
In short, folks, we're looking at Amazon launching as many as 3 devices next Wednesday, One could be a set top box slash gaming console, while the other two could be gaming controllers.
