I know SR 4 went off like a bomb for us fans getting snatched up like mad. Now I am wondering when they are going to expand on it? Seriously it been almost four months and they haven't even announced the release date for even one of the expansions. They fixed a lot of their typos and errors in 4th when am I going to get street magic and runner havens? I really want thos books for the game I am currently in. Any thoughts quips or rants?
From my understanding (and to repeat KV), the 'places' sourcebooks (i.e. Shadows of Europe, Shadows of Asia, Smuggler's Havens, etc.) are fully compatible with SR4 since they don't have any specific rules additions or changes. Any equipment in those sourcebooks would have to be looked over by your GM to be converted to 4th edition rules.
IMO, I don't think they're going to come out with any rules expansion sourcebooks like Cannon Companion and such. I believe the goal of 4th edition was to simplify and streamline the rules, and rules expansions would probably do the opposite of that.
I'll probably be trying out 4th edition in the near future, and we'll see how it goes. As of right now I think I still prefer 3rd ed, though I haven't played 4th yet so we'll see.
