What's the deal with DC Comics? (sorry if I come out sounding like Jerry Seingfeld, though last nights episode was hilarious)

I just heard the news about Nightwing, Robin, and Birds of Prey comics all getting cancelled; so that when the Batman R.I.P. arc is finished there will be a huge Batman event titled: "Battle for the Cowl"

I'm not against the fact there could be someone else that's not Bruce Wayne as Batman, but Dick Grayson/Nightwing, no!!! He's been built up so much as not wanting to take on the Batman persona he became his own hero. Grayson is a much better character as Nightwing and he'd just lose everything that makes him cool if he were to become The Dark Knight.

Tim Drake and maybe Jason Todd are more suitable/acceptable as replacements for Bruce Wayne, temporarily; cause we all know that this decision isn't going to last long. Bruce Wayne is going to come back somewhere down the line and become Batman again, it's happened in the past when he got his back broken and this is going to happen again... I just hope when this is all said and done, i will be able to walk into a comic store a year from now and purchase a Nightwing comic starring Dick Grayson.
