Interestingly, just looked at tickets for next year. Sales are going pretty well (middle Saturday already complete sell out, plys the final).
However, you may not see the regulars in their prime seats due to the change of ticketing policy. Effectively the first four rows are now "premium" seats which are around double the normal price tag. So for the first session on Saturday 15th, that's £50 plus booking free. Granted you get a programme (40th anniversary one) and earpiece, but that also means those who wanted to get close to the action and get a ticket won't be able to do so. Plus if you went to two premium session, what use is two of each for example?
With the price increases I already spotted (£25, £30 and £35 for first Saturday morning, afternon and evening, and £20, £25 and £30 for corresponding sessions during the week) it's not exactly affordable as it was. It may be the first time in years that I don't go to a session next year.
