Yesterday news hit the web that newly founded Respawn Entertainment would premiere their first project at E3 next week, but today Jason West has said that it won't be revealed at E3. Respawn Entertainment are just getting started and aren't ready to show anything just now.
Respawn Entertainment was founded by Infinity Ward founders Jason West and Vince Zampella after they were fired by Activision for insubordination. During the past few months several key members of the Infinity Ward team have joined Respawn Entertainment who are working on an as of yet unknown project for EA.
