In a statement to the website, Activision said:
‘After careful consideration, for business reasons Activision has decided not to participate in any official E3 activities. We wish the ESA best of luck with the show.’
Online reports also seem to suggest that Activision's stablemate Vivendi will also not be attending the event.
E3 will this year take place between Tuesday, July 15th and 17th at the LA Convention Centre, US.
