The folks over at Bleeding Cool report that Marvel Comics are planning a "big cosmic crossover event" which will run until late summer. According to the site, the event will begin in Nova #1 (which hits stores next month), and will be developed in Brian Michael Bendis' Guardians Of The Galaxy and the recently announced miniseries Thanos Rising from Jason Aaron (which begins this April), as well as possibly Kieron Gillen's Iron Man series. It will follow Bendis' Age Of Ultron event, and Bleeding Cool describes it as "all encompassingly cosmic, on an Avengers Vs. X-Men scale." The site also says that the event will "probably" be written by Bendis, but there's no word on who will be tackling art duties. Stat tuned to CBM for more details on this crossover event.
