Valve, releasing source 2? Naah. I think more likely during the summer big update.
Valve releasing cache (dog-shit rework) but it makes sense it will return.. only thoughts.. for what map? -mirage? -dust2? overpass? reason is 2 oldest maps, and i heard some rumours d2 could be out, but its iconic CS map..
Nerf'ing SG? I think yes.
What u think they gonna do?
