The AFL is streets ahead of the NRL in terms of professionalism and foresight. AFL is genuinely committed to expansion whereas the NRL thinks setting up a team in Brisbane's west/south is a major step forward (which is what they're planning now).
I'd agree with you Infamy, my gut feel is that rugby union could be the major beneficiary. I'm a union man - played the game growing up, and I can't believe the timing on this one for the Rebels. With a world cup in 2011, we've had gasnier going nicely in Europe and apparently he's coming back to Australia for the S15, Will Chambers is going okay at the Reds, plus I read in the paper this morning that Folau is giving the Rebels some serious thought. Now add Inglis or Cronk (who grew up playing union) and I think the Wallabies are going to have some depth in time.
Of the storm boys playing AFL, I think Slater's the one who would probably have the all-round footskills and hands to make it but he's 26 and it'll take a good 2 years for anyone to transition I reckon - no matter how talented you are. I know Inglis & Folau are still in their early 20s but I'm not sold on their kicking. It's a rarely used skill for outside backs in League and you'd need to be an elite league kick to be an okay AFL kick in my books. Cronk, maybe... pretty slow though - remember they've got to run 20km a game instead of 8km.
Karmichael Hunt's going to be interesting to watch. He grew up playing union in Brissie as a flyhalf/fullback which means he would've kicked a lot, so it'll be a much more natural transition skill-wise.
