I'm excited for some more content, in particular what they added for the PC launch. Still reading up on what multiplayer changes they're making. I'd love to see a more standard co-op system, where you can actually invite somebody you know to join you rather than finding people's signs on the ground. I get really frustrated when it takes 5 minutes waiting to see the "summoning failed" message appear.
I hope in later games they allow for a more expansive mp experience as well, with full co-op areas rather than ending with a boss fight and sending the phantom home, and more balanced PvP that allows all play styles to be viable (heavy armor/tower shield gets demolished 99% of the time, and backstabs need a rework...).
