Actually, I would think we are better off if most of the prize pool is given out in just a few of the tournaments. That way we don't have to chain ourselves to our PCs, as if we were in some kind of BJT sweat-shop, in order to benefit from any overlay. Just play in the two or three biggest-paying tournaments each day.
The size of the fields and thus the length of time it takes to complete a typical tournament might prove to be an issue, as with the current freerolls.
Ken is saying that more money is likely to be given out in prizes than taken in subscriptions during the first few months. That would be just as true if the subscriptions were $200 and the prize pool $1,000,000 (more so, in fact, since it would be bound to attract fewer subscribers).
The question of whether $20 per month (or c. $15, if you pay for a year up front), with no guarantee that you will recoup any of that in prizes, is too expensive to attract people with other expenses to pay, such as filling their cars with gas, is an entirely separate one. It seems to me that it is pitched about right.
P.S. I wouldn't recommend moving to the UK. No tournaments whatsoever, and gas prices that would certainly get your attention! Plus I hear the weather is better in California.
