Neither television nor sponsors care what the format is. They know that once they decide to invest in you, the investment will be so great you'll be tripping over yourself to adopt whatever format changes they want.
Bringing this issue up again demonstrates that you don't understand what the outside sponsors, and thus TV looking to sell your program to outside sponsors, is looking for. They are looking for an established market. If you're putting a program on TV attempting to win viewers over with your format you have already failed.
So, the combined league can pick whatever format works best for the players. I think PSP has it right with XBall and 5-man - you've got an inexpensive format that is played Saturday and Sunday only for your 'weekend warrior' players and an extended format for your high-end teams. (I think NPPL has the concept right with semi-auto, but if the unified league goes that route they're going to have to sack up and sell certified chips/boards if it's going to work.)
Personally, I think grass and not stadiums is better. Again, the sponsors don't care where your event is - they care how many people are there to see it. But, the number of impressions the sponsor is going to get from people being at the event is far, far, far smaller than the number of impressions the sponsor is going to get from title sponsorship of an event covered on paintball websites that get tens of thousands of visitors a day plus paintball media that reaches hundreds of thousands of people a month. The sponsor, and the network, simply do not care whether you are in a parking lot or a soccer complex in comparison to everything else.
Let me ask you this:
You want to televise a paintball tournament. You can have it *IN* an NFL stadium, or at a soccer complex with temporary bleachers for 2,000 people. Assume (even though it's not) that cost for each is the same. Which do you choose?
