Are we going to start allowing IA/Forgeworld units in regular tournaments? It seems like a lot more fliers, tanks, and infantry would be available to add more flavor and balance to certain armies and it would also boost Battleground sales. Also the developers look down on people that disallow IA units ;P see link

We can take this point by point.
BG Plainville has allowed FW units for certain events. (FW models are almost always allowed where appropriate.) The last Trios tournament allowed certain FW units, from IA2 I believe. But why not for more "competitive" events?
Flavor, sure. I'm on board with flavor.
Balance, almost certainly not. For every super cool thing your old codex gets, a newer codex is also getting a super cool thing. The codices are still going to have inherent imbalances. That logic also doesn't account for the units themselves being "experimental" and potentially game-unbalancing.
Battleground does not sell Forgeworld models, so I just don't see how BG sales would be boosted. Because people are overpaying for Forgeworld resin, suddenly they'll come up with more money to spend on their army at BG?
The developers also look down on competitive Warhammer. So there's that.
Also, if tournaments allowed FW models, Sam would have to know FW rules.
I'd find a way to bring Aetaos'rau'keres and you have to ask yourself if it was worth it.
Oops, now I might be late for work!
