I think most tribes, including yours (
Kalou) will be around. (at least most of the top tribes)
I think the tribe nobody is watching that will jump up and bite a few in the butt though is
ELITE, a K54 tribe. Love their layout, village points aren't bloated and they have dedicated leadership.. Keep an eye on them in K54.
Also,
-X- (they have a tightly bunched map which in a church world isn't as bad. Fast support times, heavy walls, speed 1 world so ample snipe time and multiple members to back time if necessary.
-X- is all about strong leadership, smart diplomacy... they could easily become a factor.
LETA,
AFA,
Shhh,
PLUTO.... are all sound, AFA of course is the tribe to beat with the everyone else chasing after.
The left overs, can they make a difference by seeing past their differences and actually stiffing a fight against AFA is a good question to ask. Way to early to tell yet.. Still, it's fun to speculate, yes?
Just my 2 pence
