I'd say more online satties are needed, but just doesn't get the traffic that you'd see on PokerStars back in the day. Live satellites are tough due to inconsistent demand and low profitability. I suppose I'd like to see more/better satellite options now that the STTs are dead, but I don't expect that to happen. There aren't many days where I can't find something good to play.
Any gaps in the WSOP schedule can usually be filled by something at Wynn/Venetian/Aria/Orleans/etc. The events usually run without too many logistical issues and the schedule has a good mix of variants at different budgets. Considering the scale of the event, I actually think WSOP does a good job in general. I don't have major wishes or suggestions for WSOP24. I'm guessing they'll drop some of the major event dates during WSOP-P, which seems doomed to be a train wreck.
