Beyonce Sets August Date for Surprise ‘Footprint’

What is going on in August ? According to Beyonce’s official site, something big will go down August 19.
In a message posted Wednesday, the “Love On Top” singer said “leave your footprint on 19 August 2012.”
It is unclear what this means at this point, but it could mark the beginning of a new era for Beyonce.
As widely reported earlier this year, the Grammy Award winner had conversations with Ryan Tedder that led to speculation about two projects, including a follow up to her 2011 effort “4.”
Beyonce is said to be in the studio prepping for a new album so, maybe this will be the release date for a single or some form of announcement regarding her next effort.
Any thoughts ?
