Finally my concern has been answered.
Some time ago I was wondering how DC would be able to cram one 'DC time' year worth of stories in one 'real time' year. Here is how: a weekly comic. This is a brilliant move: How to force fans to buy double by having them follow simultaneously two timelines. I can just imagine the load of retcons they'll have to do after that..
Yep, Keith Giffen is reenacting the bloody 'five-year gap'. Prepare thy doom, true believer, the end is near.
If I ever needed a reason to completely stop buying current DC, here's a pretty good one.
