Looks like it’s official now. Linksys has confirmed that they have discontinued the Linksys DMA 2100 and DMA 2200 and have no plans to replace them with newer extenders. So you better pick one up now if you want one and can find one.
Linksys Exiting the Media Center Extender Market
the past year you could pick up a Linksys DMA 2100 for super cheap
prices at various online stores. So cheap the little MediaCenter
extenders have become quite popular.
it looks like Linksys is finally running out of the devices and
officially discontinuing the Media Extender products entirely.
