According to N4G.com, this is potentially the release list for the European PSN store.
You'll notice that it lists a SOCOM Confrontation trailer for late April and a SOCOM Confrontation July release. Take it with a grain a salt as for now it remains a rumor, and even if it wasn't dates are always subject to change. So don't mark your calendars just yet! Only a couple more weeks till the EGM cover story.
