CCP typically release two expansions per year and Tyrannis has been roughly slated for this year's summer expansion. Although the summer expansion can sometimes come as late as July, CCP have just released a new teaser trailer confirming a May 18th release date. This gives the developers just over 8 weeks to get the expansion into shape. This should give the team more time to work on the next expansion, which most are hoping will be Incarna. Skip past the cut to watch the official Tyrannis teaser.
