[CBR]: Theories about the return of Steve Rogers as Captain America have been brewing ever since his death in “Captain America” #25, but the speculation has grown to a fever pitch following the release of two teaser images…

While what exactly is happening isn’t known yet, CBR News learned late Thursday that Marvel is going to support the release of “Captain America” #600 in a surprising way.

Today on the Diamond Comics Retailer Services Web site, retailers were informed via a news bulletin that they could contact their Diamond Customer Service Representative in order to receive and sell “Captain America” #600 on Monday, June 15th. This is an unprecedented move, as new comics have been traditionally only been sold on Wednesdays for over a decade, barring holiday shipping schedules.

The move to a Monday on sale date leads one to speculate that a major announcement regarding future storylines is coming on June 15th.
Adding to that is news that Marvel is rushing a second printing of “Captain America” #50. The final order cut off date for retailers to submit their orders is June 1st, with a Wednesday June 10th on sale date. Marvel hasn’t rushed a book back to print in that tight of a time frame since the President Obama related “Amazing Spider-Man” issues blew up in the mainstream press.
