Dunno about the other conferences, watch the Lions in 2012.
My gut feeling:
SA = Lions
NZ = Chiefs
Aus = Tahs
Hope we'll get competitive conferences to get the best 6 teams in the business end.
Your prediction for SA matches mine Paarl, so its obviously inspired.
Seriously, you have a good understanding of the SA scene, so I am interested that you think the Lions will supplant the Stormers. I know that the Stormers have botched their backline by failing to turn over their older players and regenerating stocks but the forward pack is still very strong. If the Lions can get over them in the constant pressure that is Super rugby they will be formidable indeed. I suspect the Bulls could prop up the SA comp this year, they will be rebuilding for next year I think.
The NZ conference will be the most interesting. The Blues are very strong on paper (they are every year), the Crusader production line still continues to pour out class players like Todd, Highlanders have the best coach in Jamie Joseph and have some good recruits but thin depth and the Canes are a train wreck. I cannot see the Chiefs as any better than 4th, they still don't have the forwards to match the top teams. You don't get to the top without enough quality in the pack.
I hope you're right about the Tahs and I expect them to nudge out the Reds on the table. I think the smokey in the Oz conference is the Force, who could be anything. Their pack is very strong and if they keep Stannard at 10 they might turn a lot of teams over. They only lack self belief. The Rebels and the Brumbies will be better than last year but still bring up the rear.
I expect the Oz and SA conferences to be stronger than last year and the NZ conference to be a bit weaker. Overall, I expect the whole comp to be better than 2011 with very few easy games for anyone. Picking a potential winner at this stage is almost impossible with all the vagaries of chance and injury.
