Come on man. Let's be real. GOTG and Punisher are a different thing. It's gotten annoying that people have been saying "Because of Guardians then_____"
Guardians had way more appeal to the masses than Punisher. Guardians has these cute kid appeal characters like Groot. It's bright, it's colorful. It's fun, it's adventurous, the characters are comedic, and it's set in space.
Punisher is a dark character, even if they make it PG13. He doesnt have any fun kid appeal characters, he's not a happy guy, he has little personality. His world is the dark, gritty streets of NYC. It's a gangster movie, it's a vigilante movie, it's a movie about a visibly broken man. Do you really think Marvel is interested in making a film of that? Do you, and anyone else, really think Marvel, who is known for being these fun action summer movies is going to release a gritty movie?
And Punisher is so different from any cinematic movie their doing, but it is more in line with what they seem to be doing with the Netflix shows. Why would they release a movie when he fits with the Netflix movie? Especially since, seemingly, all their movies are going to meet up eventually except allegedly Guardians (and I'd be surprised if Guardians never meet any of the Earth set heroes). Where does Punisher fit. Yes he's interacted with The Avengers in the comics, but I'd argue that those stories pale in comparison when they just make Punisher on his own on the streets ala Punisher Max
On another note: Are you, or anyone else thinking that Punisher or GR or Blade will be R?
And even if someone says "Well TDK was dark and it made a lot of money": 1) That was also Batman a way more beloved character than Punisher. 2) It had serious buzz around Heath Ledger 3) And it was a sequel the Batman Begins, which was a well liked movie.
All this being said, Im not saying Punisher or Blade couldnt be good successful movies, especially if they keep the budget low. I just dont see Marvel making a movie for either of them.
