Yesterday we reported a hint from Samsung’s Galaxy S Facebook page suggesting Sprint could be announcing a launch date for their Epic 4G very soon. While this isn’t official, word of mouth is that the launch will come next week, with the Samsung Epic 4G dropping on August 11th. A source said the date is referenced in Sprint’s internal employee Playbook publication, and furthermore that some stores could be opening as early as 8AM to accommodate the release of the nation’s second 4G-enabled device. We know for the hardcore hardware keyboard crowd the Epic 4G sounds like a dream come true, though next week also could see the launch of the similarly keyboard-clad Droid 2 rumored for August 12th. Can the world handle that many hardware keyboards on high-end phones? Or will it be keyboard-mageddon?
