Over at Reddit, several of ACIII's developers are currently participating in a Reddit ask me anything thread. They're defending the game from some of the most common criticisms as well as dropping all sorts of interesting tidbits about the game's development and the decisions they made.
So, when PC launches, it will include ALL of the console patches out at the time (so, that includes any patches we might be releasing in between now and PC launch). In addition, PC has a special patch designed to ensure that everything runs as smoothly as possible.
We've added extra DX11 support for the PC version, so you'll notice some significant increases in texture resolution (double-res in most cases, but quadruple in some), TESSELLATION (which is like, the new DX11 hotness) and some other shader improvements that will have an impact, but aren't all that sexy to enumerate in a reddit post, hehe."
