The amount of people who play drums now versus say 1961 must be proportionately a lot lower. There is no Wipeout or Take Five, etc. coming from the radio that made kids instinctively look for the nearest set of sticks.
Accordingly and as implied in one of the posts above, when the baby boomers die out there will be a huge hole in the vintage drum market (guitar, etc too).
That hole may be filled to some extent by up and coming markets like Asia who will have a real appreciation for good American stuff versus the good but souless stuff they spew out.
The best way to deal with this--as said--is just have fun. Quality woods and hardware will always have that intrinsic value. Things like vistalites are more susceptible to fad and one should be leery. If you are risk adverse, sell the OBP Downbeat set and keep the BDP one. Same sound without the scary premium for a finish--that's a market whimsicality, versus the BDP which is purely based on the constituent properties of the drum alone and the wrap (as long as original) only plays a contributing role to the value.
