In my view, you'll need a 3W (or hybrid, I guess) for long holes more than you can use a 4th wedge. 3 wedges then the PW from your irons tends to provide enough coverage, spacing and shot options.
Will be especially true if/when you tick over to Legend tier, when the holes get a LOT longer and even with a Driver and 3W there are par 4s that are tough to reach in two shots.
Also, there are other threads about the high-level clubs that have disappeared recently and word from all is that something similar or equivalent will come back into the Pro Shop in the next few months, so I'd hold out.
