Well with WB's announcing an official release date for The Hobbit on December 14th 2012, then WB's should prepare to set a release date for Man Of Steel on Wednesday December 26th or Friday December 28th.
That's a good two weekends apart for the Holidays, so they won't be competing head to head against each other. Man Of Steel is ahead of schedule compared to the troubled Trek sequel, which isn't even in pre-production yet.
If WB's assigns Man Of Steel a Dec 26th or 28th release date, then Trek may wind up getting squeezed in between Hobbit and Man Of Steel on Friday Decembr 21st?
Bad spot for Trek if that winds up happening and good spots for both The Hobbit and Superman Man Of Steel...potentially of course. WB's needs to snag the Dec 26th or Dec 28th release dates for Man Of Steel asap!
