@arturocalakayvee: Probably the Ultimate Universe because marvel have pretty much killed with repeat beatings from writers like Jeph Loeb, Sam Humpheries and Joshua Hale Failkov. Also Marvel once said if the universe ever crossed it signed they had officially ran out of ideas and now bendis is obsessed with having the universes cross over. So there's literally no point keeping it, which is shame because it was so brilliantly ahead of it time in its first 5 years, Literally influenced so much of marvel media portfolio.
However, Age of Ultron was supposed to be summer event of 2012, until marvel at last minute abandoned it and had bendis re-write the ending. Avengers vs X-men was rushed together and Marvel Now re-launch of most of the portfolio still happened as planned. One can only assume that Age of Ultron was going to be like flash point and reboot the Marvel Universe until marvel cold feet (can you blame them after Heroes Reborn). Maybe Hickman is going new 52 the marvel universe Crisis on Infinite earths style.
