My $0.02 on the men:
The Aussie Open was a great event, and it showed some things. First, Ricky Wisocky is ready for another big year. His putting continues to be awesome, he continues to throw extremely accurately, he's dialed in, and it looks like he's still motivated to win.
Eagle played a great Aussie Open, and he'll be challenging the others in 2017. He's still young, he's still gaining experience, but he has a tremendous game and will only improve, IMHO... provided he doesn't let the close loss at the Aussie Open affect him mentally.
Simon Lizotte - before his injury he was beginning to win tournaments. He won in a playoff over McBeth and Sexton (don't remember which tournament), and was looking poised for greatness until his injury. If he can overcome that and get his game back in shape, he'll be a top-tier challenger. But part of overcoming the injury is overcoming the mental aspect of it all...
Big Jerm is now with Innova. Switching discs might hold him back some this year, but IMHO he'll begin to to challenge more and more as time goes on. Big Jerm and Innova will be a monster matchup.
Nate Sexton... I think he's the one that is going to have to win a big one to get over the hump. He has the skills, he has a solid game and good decision-making... but he lost to Ricky in a playoff last year in a tournament he should have won, he's lost leads very late in other tournaments... I'm less worried about Eagle's mental game when it's all on the line than I am Nate Sexton. I really hope Nate breaks through.
Philo has flashes of brilliance, but is often up-and-down, hot-and-cold, on-and-off. If and when he hits "on", it'll be "on", fer sure.
A bunch of other players have been named in the thread, and any of them can pop out and win a tournament here and there... someone may break out and begin competing with the very top players.
And I saved the best for last: McBeast. I was (unhappily) surprised at Paul's 2016 season. I know he was injured, and I hope he fully recovers. But I did not understand his play at Worlds... he was throwing out of bounds a lot, seeming to take too many chances. Ricky played conservative at Worlds and built a huge lead. Sexton plays conservative and is in the top-tier. But Paul had a lot of damaging OBs at Worlds, and a few at this year's Aussie Open. I hope he gets his mental mojo and course management thinking back. If he does, I think he can begin crushing Ricky again. If not, 2017 will be like 2016 for him. Paul's putting is becoming stellar again (as Ricky's continues to be), and if Paul stops the OBs at inappropriate times (meaning every time), he'll start winning again.
TL;DR - I want some McBeth 5x discs. Make it so, Number One.
