Interesting. I'm actually kind of impartial on this. I know my team and companion team would most likely bowl all of them, but I could see a case of entries dropping in the 4th or 5th straight year going back to Reno. I do understand the benefits from a USBC standpoint, and from a prize fund standpoint. Much less expensive for the tournament in Reno, meaning more money into the prize fund.
However, I can see the people that use Nationals mainly for a vacation getting sick of going back to Reno a few years in a row, not bothering to go back the following years. Depending on what travel costs and entry fees (including additional fees depending on how you pay) will be by then, people may use that money to take a full vacation instead of making a vacation out of the Nationals trip.
I don't see it being an issue the first couple years, but after a few years my guess is a pretty considerable drop in entries.
