I found this on one of the Wikis you mentioned and I assume it's one you want changed.
Replace your current message with:
{{#switch: {{{1}}}|confirmed=This product has been announced or verified to be discontinued by the manuafactuer. Link to verification: {{{2}}}.|assumed=This product has been assumed to be discontinued by the manuafactuer, though no official word or verification ahs been given, it is rarely spotted on retail store shelves.|#default=This product has been completely discontinued, it is no longer avaliable for retail sale.}}
The "1" parameter is what this function will check the answer to and should probably be renamed to something of your choosing ( "{{{discontinued}}}" would make sense). "assumed" is the answer that will produce the first message. "confirmed" is the answer that will produce the second message. And any other answer (or none) will produce your default message. The "2" parameter is what will display your link (i.e. [http:wikipedia.org Wikipedia]) and again should probably be renamed ( "{{{link}}}" would make sense).
Does this help?
