What you have to remember about age 65 is the effects will never go away. Sure in 2 years people will start retiring. But the effect of age 65 will last forever. Based on the trends we've seen, almost everyone is working until age 65. It basically means every pilot has the ability to work an extra 5 years. That means that things will always be slower than they were before age 65. It means a good 20-25% fewer pilots will ever reach a major airline because those currently there will stay longer.

Waiting for the effects of age 65 to calm down is a bad idea. The effects of age 65 will never go away.
