Secret Wars just became available on the iphone app. Worth a read.
DC is doing something relatively ambitious:
Newsarama.com : The DC UNIVERSE Reboots in September, New #1s Across the Line
They've basically hit the reset button on 52 titles, trying to lure new readers and also clean up the continuity problem that is going to plague any story that has been ongoing since the 60s. Not unprecedented.
1) Marvel started the Ultimate series (new spiderman, x-men, avengers, fantastic four, few others) in like '99, although they kept their old storyline, and just had two. The Ultimate comics were pretty good, tried to be a little more "realistic", as far as you can be realistic and still be talking about teenagers with spider powers, etc. But realistic in the way that the movies are less cartoony than traditional comics. In fact, the Captain America movie seemed to have been based off the Ultimate Comics. Also, Ultimate Nick Fury looks exactly like Samuel L.
2) At one point, the X-Men titles all got reset into the Age of Apocalypse. Marvel "pretended" that it was a permanant change but they only made it last 4 months, working the hiatus into the plot of the ongoing series. It sold a ton of comics, and was actually really, really good.
3) At another point, Marvel and DC announced that they were both going out of business and decided to merge. This was purely publicity to try to sell a crossover. Looking back, I'm annoyed that I honestly thought it was a business move. Stupid gullible me.

Anyway, I don't read DC comics very much, but I'll read some of the reboots, give them a chance. The Justice League, which comes out today, is drawn by Jim Lee, so it can't suck. One nice thing they're doing is releasing print and electronic issues at the same time. Smart move, since I think they probably make more money through iphones/ipads than print, might as well embrace the shift. I'll post reviews if they're worth a read.
