For the most part it seems they're just rolling anti-virus tools directly into the products they protect (as they have done with Windows 8), which seems reasonably sensible and it's probably a necessary step to let go of the enterprise management tools of these, to give the Security Partners some assurance of a future.

ISA-Server, aka TMG, is probably the only "real" casualty in all this. But there's an obviously compelling argument for suggesting that if you want to go with a Microsoft solution for remote access to the network, you are leaps and bounds better off planning migration to DirectAccess than considering another version of TMG.
