At this point they won't have a achievement system till Sony/Microsoft have a open API for them. It was just to much work to keep them from breaking every now and then since they weren't that open about what they were updating behind the scenes etc. Our best chance is if the new consoles make it easier to obtain the data so they can put up a new achievement sync without having to worry about it breaking at random times.
Unless the PS4 looks like it won't have much support game wise I'll be picking one up. Microsoft will have to show quite a few new IP to even get me interested in the next Xbox. Most of the games I would want to play on it will be third party and my PC is more than powerful enough to handle it.
I've always liked the DW games so I'm most likely going to pick this up fairly soon. The first game in this series was also quite fun and I actually got a platinum in it. I guess beating up random guys over and over never gets old for me.
