See this is what I totally agree with you on and what I really like about this idea. Just one big series of events that line-up all together to tell you what is in continuity, who exists,what is coming up, and even who is new to the universe. I feel like its such a straight forward idea to explain the history without rebooting it. Of course we can probably expect one or two retcons here or there but lets face it thats pretty standard for comics at this point.
