The trouble is Nikon might just come up with an AF-S II version of it in their next iteration and then it may not be worth as much |sigh|...

Hurm. Well, looking at it on a purely financial level, if you paid on the higher side for the lens, selling it now "protects" you from a loss. However, if you purchased it earlier for a less stratospheric price, it's purely a "paper loss", in that you wouldn't realise the maximum level of return on the lens.
I do think that the lens is close to the net maximum it's going to see in terms of price. It might get another 10% or 15% higher, but there's likely a limit for the specific qualities of the lens coupled with the total number of these that were manufactured. It's not like Nikon only made 500 of the lens over the years, after all.
From a photographic sense, if you're not using it at all, don't get a lot of satisfaction from the lens (no slight intended - it's not a lens that every photographer wants or needs to use), and find it just gathering dust, perhaps selling it is a good move. OTOH, if it's an occasional use lens that's
exactly the lens for you when you pull it out, it's a much harder call.
Judging from eBay and the Café of late, if you set a selling price a bit below the current peak price, it'll likely sell quite quickly. To put this in perspective, I haven't listed my 28mm f/1.4 and have no plans to do so; so you may draw what conclusions that you wish about my advice and its impartiality. :wink:
I hope that this helps.
