This really shouldn't surprise anyone, but G4 has announced that they are ending their long running shows X-Play and Attack Of The Show. An announcement over TV Guide indicates that new episodes will play through December. A series of guest co-hosts are expected to rotate through both shows, which are likely to be doing a lot of retrospective pieces leading up to their closure.
By the time they close, AOTS will have over 1700 episodes aired, while X-Play clocks out after 1300. Long time viewers and astute observers will recall that Adam Sessler left X-Play back in April over a contractual dispute. It is probably a safe bet he will not be reappearing for the finales.
Meanwhile, G4 has not yet announced what will replace those programs. The network has been moving away from the tech-oriented focus of its earlier ZDNet iteration for years, and suspicions are that they will undergo a further name change in their quest to pander to the "young male demographic" more obnoxiously than Spike.
