Truth? New regime at DC, it was Levitz who prevented the crossovers, April solicitations are due soon and... it was on Diamond's site in the news section.
Well true, there is a ton of old 90s Marvel guard there now. Still, not like DC is ever bringing back that Joe Quesada created character Jean Paul Valley anytime soon though.
Don't you think they if they did have a crossover book again they release that information at a con or one of your sources throughout both companies would leaked this and not through simply Diamond? I mean come on you found out Watchman stuff via that. Such a project could never be that easy if ever announced. Like I said a source of your's amongst either company would give it to you first with actual proof or they'd release it at a con.
Still, if you think the wounds have healed and Avengers/JLA won't be the final crossover. Well..here's to hoping for that.
