Regardless of Pietro Maximoff's valiant sacrifice for Hawkeye and an unnamed Sokovian child in Avengers: Age of Ultron, fandom had never felt that it was truly the end for the character. After all, the Infinity Stones - which with all their combined power undoubtedly have the ability to bring the dead back to life - are still floating around almost four years later. Not to mention, Quicksilver was such an under-utilized character, definitely in contrast to twin sister Wanda Maximoff (Elisabeth Olsen). Sketchy Eastern-European accent and comparisons to the X-Men version aside, the MCU's Quicksilver has his fans, and many more would like to see the character reunited with his sister for emotional catharsis and a deserved second appearance on the big screen.
Rumors have abounded that Quicksilver may be back in Avengers 4, opening up the possibility that he will find himself brought back to life akin to the snap victims. However, that may be wishful thinking. Actor Aaron Taylor-Johnson has recently gone on the record as saying that another appearance for Marvel Studios is "not a conversation" that's being had right now. Whether he's employing the time-honored MCU actor's traditional tactics of evasiveness for the sake of protecting spoilers or actually will not be returning, the lack of word makes it seem any appearance would be a flashback, rather than a future tease.
Although Crossbones met an untimely end at the opening of Captain America: Civil War, actor Frank Grillo has spilled the beans and revealed he will return in a "flashback" in next year's Avengers 4. The set photos revealing an aged Tony Stark and seemingly-present day Scott Lang being present at The Avengers' Battle of New York suggest time travel of some sort as a certainty, so Grillo's quote holds up.
What's not so certain is Crossbones' return after Avengers 4. With the character firmly vaporized and his next appearance touted as a flashback, it's unlikely that Marvel is planning a long-term resurrection.
Following Guardians of the Galaxy director James Gunn's firing from Marvel, Dave Bautista has been very vocal about his unwillingness to do a Guardians of the Galaxy Vol. 3 without him, tweeting that it was "nauseating to work for someone who'd empower a smear campaign by fascists".
Of course, he's still contracted to do Guardains 3, but with the production at a complete, indefinite standstill and The Eternals filling the cosmic hole in 2020, that may be a long way off or retooled. As such, Avengers 4 could well be Bautista's somewhat unintended swansong for the MCU.
