Actually - lets take a vote - wave 8 will consist of the above mentioned OTC units, and units / vehicles from which Race:
Click here for racial backgroundsAvains : finish them out with giant bird/dino cav and their massive winged avatar
The Grud : Get these brutes started - lots of heavy stuff and plenty of tunnelers, etc.
The Legion : I'm thinking these guys will eventually "retconned" and merged with the Sectnids conceptually.
The Lyceum : Steam punky / gothic robots and vehicles, many of them quite large.
Pharon : Egyptian themed army ala "Star Gate".
Sisterhood: Additional Tanks, flyers, walkers, etc.
Sctinds : Start working on the "Big" bugs...
Stygian: Flush out the line with fliers, command units, maybe some bigger vehicles...
Tzacol : Get these Mesoamerican themed lizards started.
There's a couple of others that can be worked on that aren't listed:
Denizens : This line will include a number of random units that can be found throughout the universe, like fanatical cultists, armed civilians and gangs, limos and other civilian vehicles converted for combat, etc.
Hellborne : Demons and hellish monsters and their deluded worshipers.
Terrans : Human fighting forces, divided into different factions, but sharing common war gear.
Forsaken : Engineered human soldiers driven from the Terran worlds in exile due to their uncontrollable nature. They Cobble together ramshackle war machines from scrap.
