What is next?
Probably a year or two or three of Superman, Jr, then a return to the status quo. Welcome to comics, where the only people who stay dead are Uncle Ben and Gwen Stacy, and even then there are exceptions.
Will he wear a dress and lipstick?
That would be Supergirl. Maybe you've heard of her? Had a bad movie, had a tv show that went on too long and seemed to lose the point a few seasons in?
Will his Cape and Red Tights have Lace?
You're afraid that a dude who wears a cape and tights might add something girly like lace? Honey, he's just one chiffon wrap and a pinkie ring away from being flying Liberace as it is.
Will he now speak the Communist Languages of Chinese or Russian?
It is canon that Superman, having a superhuman intelligence, already speaks those languages. Because, you know, he saves the world not just the truck-nuts-owning portions of it.
Will we in American have to “Press One” to hear a cartoon or movie in English?
And wouldn't it be just awful for you to have to learn a new language?
Also, subtitles do exist. You can read, can't you?
