I wouldn't say it is just yet. Remember, when something dies it is theoretically unable to be brought back by conventional methods. Considering we can still prevent certain things and still bring the site back up to speed, I wouldn't consider it dead just yet. So long as there are active staff, the leader is sticking to the site, and a few members are retained, we can still make an easy comeback.
Furthermore, there are currently a lot of plans underway to help revitalize the site. So I would just give those a little time before we start stamping 'Dead' onto the site.
