I see some revolvers I want are discontinued and no longer available on the s&w product list. Do you think the wholesaler still has them in the warehouse yet?

Probably not; how long are they discontinued?
I'm afraid your best bet is going to be the resale market. Wholesalers like to move the product. Having small amounts of discontinued inventory costs them money, so they're more likely to blow it out at a discount than keep stuff just to get full price.

Also realise that discontinued doesn't always means discontinued. Because model like the 610 suddenly show up every 10 years or so.

I would suspect it would depend on which warehouse and Country its in as to wether any stock is left over. The sales demand can vary from Country to Country as well.

I want nickel finish revolvers. I know when I open the door on the safe it’s going to be blinding I’ll wear my sun glasses. Lol

I have a new unshot s&w 29-10 6.5” revolver in blue I purchased on a whim for $699. I really wanted one in nickel.
