Yes, but not every owner will sell ASAP, and I suspect that number will be very very small as the new features are mostly likey not "must have" for a large majority of owners . Only a few of us online addicts are on top of the latest breaking news, and demand the latest and greatest features, and want to pay as little as possible. The fact that you may see a handful for sale at Audiogon is a pinhead compared to total units sold.
As you are "in the know", you should hedge your bets and sell now before the word gets out which may reduce the value of your uinit. Yes ? Currently there are none listed at Audiogon.
Also, a brand-new unit is always worth more than an upgraded older unit, even if the manufacturer says they are 100% identical. That's just the mentality out there at the buy & sell sites. But in the IR case, it will require a unit swap, not internal board upgrades, so you will have a brand new full-value unit.
Selling is always a hassle. So by rights, not having to dispose of your old unit yourself is worth something to you, so you should expect an even lower trade-in value from IR. Yes ?
Personally, I think a 50% trade-in value is fair ... to both IR, their dealers, and the end-users. Let us not forget there are dealers involved who also need to be compensated, if an upgrade path is offered to end-users. To think a dealer should be shut-out of upgrade profits, however small, is unrealistic.
Who knows what internal political forces are at play and how they view loyal customers versus maximizing profit. I guess we'll see what happens soon enough
