From their website:
By popular demand, Privateer Press will be postponing next week’s scheduled XGL Live event until further notice. We’ve chosen to do so in order to make the event more accessible to participants who are currently preparing for the upcoming Shattered Grounds WARMACHINE league. We apologize for any inconvenience this may cause for players planning for the XGL event, but we feel the extra preparation time and the opportunity for greater player involvement will make for a more exciting event for everyone. Please watch our website for details on the rescheduling of XGL Live.
