From what i've seen there have been a number of rookie players this season who will be at the top of the pile in a few years time:
Brett Firman (St George/Illawarra)
Billy Slater (Melbourne Storm)
Benji Marshall (Wests Tigers)
Kurt Gidley (Newcastle Knights)
I'aefita Paeleasina (NZ Warriors)
There are probably quite a few that i've missed but those are the ones that have stood out recently.
Apparently the Warriors have unearthed an awesome 5/8th by the name of Marcus Perenara but we'll have to wait & see.
