Paul O'Brien writes at The Beat:
After a quiet May, things pick up a bit this month. The big event of the month, of course, was CAPTAIN AMERICA #600. Meanwhile, Dark Reign continued to sprawl over the rest of the Marvel Universe. The more notable tie-ins include WOLVERINE’s relaunch as DARK WOLVERINE, and the start of a crossover between UNCANNY X-MEN and DARK AVENGERS.
It’s a quiet month for new titles, though, with only one new book - the fortnightly X-MEN FOREVER.
Once again, Marvel had the largest share of the North American direct market by a comfortable margin. They beat DC by 51% to 29% in units, and 45% to 27% in dollars.
