For a lot of tourney players nothing much is going to change. Sure, a rule here, a rule there that add up to some minor changes but nothing major. I think this New World Order talk is perhaps overblown--even if some arrangement is agreed upon between the PSP and MS. Yes, they will be the leading tournament series but they don't and won't have a monopoly on tournament paintball. Most tourney players don't play in either of them and if either league makes enough decisions that alienate their customer base whatever they agree on won't much matter. What the next world order does offer is the possibility of formalizing and stabilizing the game/sport of competitive paintball. And that could be a very good thing.
Here's some of what I think you can expect. 5-man in a couple of variants; xball & something (very) similar to the way the PSP has been running their regular 5-man. At the lower divisions of xball play I don't expect (and continue to hope) there are no major changes. There could very well be more divisions of both xball and 5-man. The place where the greatest changes are most likely is at the top because that is where the widest divergence between the PSP and MS currently exist. I hope, for purely selfish reasons, that the end result is either allowed some flexibility or looks much more like the PSP version than the MS. The tension is between keeping the pro level game the format's undisputed flagship competition and the pressing need to reduce the cost of competing at the pro level. There have got to better ways to address those needs (and there are) than watering down the game--again.
On issues like locked divisions and restrictive non-sponsor possibilities I won't hazard a guess 'cus that's all it would be. I will say it strikes me as borderline insane to do stuff like that at the same time you're trying to forge a world game identity for your version of competitive paintball.
One of the critical discussions to be had as the next world order begins ought to be about what has been lost as much as on what has been gained. What, if anything, can be done to regain or restore some elements of the game play that may be seen as lacking or lost. Who knows, maybe it won't be much of anything but if one format is going to dominate and become the world standard that version of the game has an obligation to represent as much of the energy, excitement, thrill and skill as can be stuffed into it.
More intriguing is what will become of the NPPL brand? I smell another cynical VFTD game.
