After yesterday's reports that Comcast is trialing a cable box that also accesses content from the internet, Light Reading Cable has received this image purported to be that "Parker" box, built by Pace. Light Reading also mentions Samsung boxes may be in use during the "Xcalibur" test program as well. Of course, even more than widgets, the possibility that adding IP services to the box could mean an upgraded guide experience is probably the most exciting possibility, but until we get some concrete evidence consider our optimism levels set to mild.
