Third time still a charm?

If you follow this sort of thing, you probably already know DC's plans to launch yet another weekly series once Countdown wraps up. This time around the series (which will be called Trinity) will focus on the Big Three, namely Superman, Batman and Wonder Woman. Shorter backup stories will also be featured.

This is all well and good, and frankly sounds more interesting than Countdown ever did, but I have to ask: Do we really need another weekly series?

Personally speaking, I'm not sure I could afford committing to a weekly, in terms of either money or interest. Plus, Countdown was weaker than 52, which isn't exactly inspiring. What happens when you take a concept and make a copy of a copy of a copy? And will this really stand on its own (as it's being touted), or will it just end up another way to tie in the overblown "events" DC (and Marvel) are so fond of nowadays?

I don't know about you, but for me the idea of another "big" weekly book is a lot less charming the third time around.
