Nyko Technologies has shipped its highly-anticipated Xbox 360 accessory line-up; the Intelligent Remote 360, a universal smart remote for the home entertainment center, and Intercooler 360, a compact, snap-on cooling device for the Xbox 360 console. Xbox 360 owners can fully immerse themselves in the next generation of gaming with Nykos stylish and practical options for the Xbox 360.

Intercooler 360 - a high efficiency, snap-on cooling device that uses three fans to dramatically increase air flow out of the 360. The Intercooler 360 reduces heat throughout the Xbox 360, promoting extended life and reliability of the components contained within. The compact, cooling device snaps onto the back of the console, fits in entertainment centers with the 360 in a horizontal or vertical position, and turns on and off automatically in conjunction with the 360.

Intelligent Remote 360 - a sleek, learning remote with back-lit buttons that allows users to control their Xbox 360 and television with the same device.
The unit picks up a signal by simply aiming the source remote at the Intelligent Remote. The product "learns" commands from standard remote controls, no programming is required. Nykos remote is ideal for gamers who have already made their Xbox 360 their entertainment centerpiece.

Nykos Xbox 360 accessories are now available at GameStop and EB Games (MSRP $19.99 each).

Id be interested in the remote if its any good as a universal remote.  And for $19.99 that seems too cheap for it to be good at it.  At least the design of it seems well laid out.  And the fan, lets make something thats quite loud even louder.  It also doesnt get around the restricted air intakes, those 3 fans arent going to help much, I wouldnt believe the "dramatic" part of the effectiveness.

MadCatz is expanding their line of Xbox 360 peripherals with the release of their new Xbox 360 Microcon Controller. The Microcon is quite similar in design and function to the MadCatz 360 GamePad Pro, which impressed us months ago with its nice analog sticks and solid shoulder buttons. In fact, the only major differences between the Microcon and the GamePad Pro are their size and the texture of their plastic.

As the name suggests the key point of the Microcon is the fact that its small, very small as a matter of fact. Compared to the GamePad Pro and official MS 360 pad, the Microcon is a good 30% less bulky, most similar to the original Playstation controller in overall measurements. Face buttons and the d-pad are all slightly shrunken compared to the GamePad Pro, as are the LB, RB, and Triggers. Analog sticks remain the same size.

I wonder if it will be 30% cheaper too, however I hope that isnt the final colour.

Inbuilt display and LED timing sounds like twoddle.  I bet the timing relies on you pressing a button on the controller to start and then for you to press it again to stop.  Its gives feedback but is it like proper forcefeedback?  I doubt it  Incredibly expensive for what it is in my opinion.
