Hey Pete! Hope you are well!
I don't know if I see collector's dumping their e98s just because they fear dropping prices. I know for myself, I don't really care if they drop or not, I'm in it to finish the set because I'm a collector working on a project...heh...I'm not worried about their resale value because I have no interest in parting with mine. I think there are quite a few others that would probably feel the same way.
But, I do see prices dropping with the raise in supply. I see the highgrade BSF cards going to set registry guys and highgrade collectors for the most part. I don't see new entrants into the hobby really pursuing these, as e98s in this nice of condition, generally speaking, aren't exactly affordable for new collectors. BUT, new collectors would pursue the low to mid grade dupes placed out on the market by the highgrade/set registry guys if they're able to upgrade. My thinking is that eventually, once the bulk of these cards start hitting the market, the high grade guys will upgrade, leaving their low-mid grade dupes on the open market which will create the increase in supply on those levels too...thusly creating that "trickle-down" effect I mentioned - causing prices to drop.
We'll have to wait a couple years for all this to play out of course, but sure, I can easily see e98s falling into levels of availability that are akin to e93s, e101s, e102s, etc...
I'd also agree with you on your assessment of the BSF e98s finding their way into your own personal collection - many of my own e98s are lowgrade and I'd be truly surprised if even one of those nice, fancy BSF examples made it's way over here
