you want us to predict something that is in a flux that is several organizations with varying methodologies that for teh most part has a widening fanbase(and pools of fighters) with their own preconceptions and thoughts on the matter over a 20 year timeframe with no real idea what may be injected into it during that time?
you don';t really halfass this question thing don't you?
but to answer your question really I do not foresee much surface difference there will be ebbs and flows but I think things will as a whole not that different the nitpicky details of their ways of doing things will of course change a bit but I see it as basically see ti as the same animal just with new faces
