The Sure, Why Not's:
Leonardo DiCaprio - he tends to pick interesting projects and has the clout to get them made. Whether he ends up like Peter O'Toole, with eight nods, no wins and an honorary Oscar toward the end of his life remains to be seen.
Cate Blanchett - she's already the Meryl Streep of her generation. The next nod is only a matter of time.
Meryl Streep - the lady herself will almost certainly be back a few more times before fading into the sunset.
Chiwetel Ejoifor - the new Denzel Washington? Could be.
Lupita Nyong'o - has the potential of going where no African-American actress has gone before. Her fashion sense has already seen her compared to no less an icon than Audrey Hepburn. I can see her in remakes of Hepburn's Roman Holiday; Sabrina (even though it's been done unsuccessfully before); Breakfast at Tiffany's; Charade and even The Nun's Story or similar projects of her own.
Michael Fassbender - definitely now that they finally seem to know who he is.
Jennifer Lawrence - yes, many times unless she gets bored and chucks the whole thing.
Amy Adams - yes, but no. 6 may be a few years away.
Alfonso Cuaron - now that he has the clout.
Steve McQueen - nothing can stop him now.
Judi Dench - with her advanced age and failing eyesight it's doubtful she'll be given another major starring role, but could still show up in support.
Matthew McConaughey - we'll see how long his recent good fortune lasts, but like his buddy Lance Armstrong, his self-serving attitude might end up doing him in.
Jared Leto - a chameleon capable of doing great things but only he can decide whether his music or his acting is more important to him.
Christian Bale - another chameleon, but he'll have to pick the right projects.
Sally Hawkins - if she chooses her roles carefully.
Julia Roberts - possibly but just as possibly not.
Sandra Bullock - will probably never have another iconic role , but you never know.
Martin Scorsese - more likely than not, but he's getting on.
Alexander Payne - maybe yes, maybe no, I can see him being recognized for his writing more than for his directing in the future.
David O. Russell - only if they don't tire of him.
Bruce Dern - he'll continue to get work as long as he wants it, but Nebraska was his high water mark.
June Squibb - few heard of her before; few will hear of her again.
Bradley Cooper - could surprise, but he's really a lightweight despite his back-to-back nominations.
Jonah Hill - not unless he gets very lucky.
Barkhad Abdi - nice guy, but sadly his opportunities seem very limited.
