I never thought or hoped Bale would come back, i just stated how i wished it had panned out that he took a break after the trilogy, then came back for this new universe, to tie it in - was just wishful thinking.
Part of me wants Affleck to continue, but it needs to be a damn good movie to erase JL from my mind - his portrayal in BvS was great to me.
Thing is, i like WW and Superman, there is already an Aquaman movie and Shazam in the works. So move forward with a WW sequel which is set in the 80's, a GL movie that could be in any decade as it is based in space. Then as i have said previously, a MOS2 which is set months after MOS - then hopefully AM is stand alone, so reason for this, these 3 movies are all before BvS and therefore, stand alone.
Shazam, AM well received. WW and MOS do great, GL too.
Then dust off the cowl and have a decent stand alone Batman movie where it's almost a heist movie involving arkham - either Bruce is breaking in or out, stuck in there not too sure.
Then we have a point where BvS happens and JL in the time line, but we can take it up to a year later and carry on with Solo's - then we can Flashpoint it as a cool way to reboot the series. That way we have a trilogy of WW's all set before BvS, MOS1& 2 before BvS then MOS3 after JL. GL1 & 2 spread out over time and stand alone. You get the picture.
