Apparently, Marvel's long-running "Uncanny X-Men" title is now canceled, the final issue being # 544. The Associated Press, via USA Today, explores the matter and Cyclops' rather expansive role in recent story arcs within. (For obvious reasons, beware comic spoilers.) Time will tell if Marvel will end up rebooting and re-numbering the series, as it was done with Spider-Man, Thor and others. (Ironically or not, they were eventually returned to their original series numbers in the past several years.)
I'll leave the matter open for everyone else to figure, while I go and form my own thoughts. Nevertheless, it is a regrettable loss. Special thanks to the Four Color Media Monitor blog.
