Personally, I doubt the Tau will be able to expand much more than it's current size, taking into account their travel technology, their size, and the fact that the Imperium is far, far larger than the Tau. While not totally impossible, the possibilty is quite slim. The Tau just won't have the ability to reinforce their new worlds in time, as their warp drives are five times slower than the Imperial ones, and they'd lack the troops to stop the endless tide of Imperial Guardsmen trying to stop the xenos from overruning humanity. The Tau will be wiped out seems more of a possibilty than them expanding any further, as up until now, the Imperium has been "kind".
