I'll wait for an official announcement before I get excited. But awesome all the same if it's a go. Be quite a step for them though. All the other total wars have different factions with their own special units, perks etc. But this will be whole races, with completely different....well everything, units, abilities, buildings.
In any case I hope it's better than Mark of Chaos, wasn't awful, but it had no staying power. Although it was almost all worth it just for that epic cinematic.
