Anyway, here it is. It's built for Nova Open 2012, which will be limiting its lists to 1999 points so there is no multiple detachment shenanigans. In addition, I'll be making use of Space Marine allies in this force.

The idea is to have the IC's join the combat squaded bike units, to create two mobile melta units and two mobile counter-assault units. The IC's will do the bulk of the damage in the assault phase, but they aren't designed to be hugely powerful in CC. However, they can harass the flanks of your opponent's army and now have the durability (due to having a permanent T5 and "Jink") to survive hits. Between these Biker units and the two Crusader squads camping home objectives, you'll have 6 Troops squads available to adapt to the changing battlefield. The shooty squads will "hide" behind the Aegis Defense Line and keep the Quad-Gun firing throughout the game, while sitting on their objective.
In addition, the heavy hitters of the army list are the dual-AC terminator squads with tank hunters. While TH changed in how it works, it also greatly improved it's chances to damage an enemy vehicle. Re-rolling the armor penetration dice also gives you a greater chance to "proc" a rending roll. Never a bad thing, especially when firing at higher AV vehicles. The new edition is going to require huge torrents of fire to do damage, and these guys fit the bill perfectly. Plus, with the added "durability" of 2+ armor (via Power Weapon nerfs), you can expect to see quite a bit of it on the board. Between the high rate of fire and the rending, you'll have a good chance to kill a few in the shooting phase as well. ;)
As was noted, the Aegis Defense Line is there to provide cover to my shooty squads. The Quad-Gun will help ensure that Flyers/mech stay honest (though the Necron ones will still get through), but it can also be directed towards infantry as well. To help in that role, we'll also be taking the Stormtalon Gunship. This guy will definitely be useful for shooting down enemy flyers, but it's a little fragile so don't expect it to last super long. Between the two, flyers shouldn't be much of a problem.
The list is pretty simple, but it'll work quite well in the new environment me-thinks.
