Can't tell if that is a rhetorical question, but... There is a likelyhood that there will be another SAS game, however it is unlikely that it will be for the 'free' online players and more for mobile and stream players.
well I said "til" so if no new one ever comes out, the wiki's dead forever
There is a new SAS in the making, but there's no other news of it yet, and it's unlikely there's going to be a flash varient.
oooooh yay! Theres going to be a mobile version yes?
Considering NK has moved to mobile gaming, it's very likely that's what it's going to be on, but not for a while, so don't keep your hopes up just yet.
Meanwhile at NK:
"A new game ay?"
Sas 4 remastered.
