You'd have a point if it weren't for the fact that Joe Recballer is also the group with the largest number of new additions to the game. And they are easily drawn into the new standard. All it takes is a salesman.
Here is all we need,
the choice depend of shops,
I'm afraid if shops want to sell .50, they will ..
Whatever the "old" paintball player is.
Lot of new people are starting every day and ask evertything to shops, and if shop sell him .50 caliber, they will take it.
.50 could be the BEST, if shops/salesman don't want to sell it, it won't happened; opposite is true ...
Nothing else to add
