Funcom's Erling Ellingsen has told VG247 that the reveal for The Secret World at PAX will be "the biggest thing on TSW yet." which is certainly a statement that delivers a lot of excitement. However, beyond the confirmation of new details being revealed in Seattle, WA on September 4th through the 6th, Erling's lips were sealed.
Rest assured that Massively will be speaking with Funcom, potentially with a high amount of fervor. So if you're looking for that new info come the first weekend of September, it should be awaiting your acumen right here.
