you are, actually.
Through my journey across the new "wilderness", my party and I found two different entry-points for quests that "weren't available", and believed them to be the new raids...
After getting flagged, it turned out we were right. The two raids can be queued up at the same time, take place in different areas of the Cannith Manufactory, with different bosses. The wilderness is also a raid instance, so if you summon a hireling, no one else in the party can enter the wilderness.
