Agreed. At the very least, both will break $200 M domestic (which to be fair, neither character was that far away from it in their first films) and $300 M foreign.
Right now I really like $650 WW for Thor, and $575 WW for Cap.
As for this whole Guardians vs Captain America argument, I'm a big big big fan of the Guardians of the Galaxy, but there's no way they're outgrossing Captain America post Avengers. GoTG will outgross Cap's first movie, but not TWS. I expect GoTG to land in the same range Thor's first film did, based on good will towards the MCU post Avengers.
Ant-Man I'm coming around to. After seeing the test footage, I can see a combination of good word of mouth and goodwill towards Marvel Studios (as well as being released six months after A2) driving Ant-Man towards a $350-375 M gross.
