Is this a BG-E2N grip?

I was looking at Ken Rockwell's site on the 50d and noticed something a bit odd. He's got a photograph of a 50d with a grip on it but it's very different from my BG-E2N. In Ken's picture, the grip has a small LCD and 3 buttons on it, just like the camera. One of them is the AF ON that my BG-E2N is lacking.

I'm not sure if it's OK to post a picture that isn't mine, so here is the link.

The picture I'm referring to is a little more than halfway down.

Does anyone know what grip this is and if it's available?

Thanks!

no, it's not. It's one of the WFT (wireless file transmitter) grips.

Nice grip tho ..

Unless I strike oil, I don't think a wireless file transmitter will be in my future. It is a very nice grip. Thanks for the speedy response.
