I don't think any genre is really dying.
Point & click/tip adventures for example:
Ace Attorney series, Hotel Dusk, Another Code games, Time Hollow, Secret of Monkey Island: SE, Broken Sword: DC, Tales of Monkey Island, A Vampyre Story, Ceville, The Book of Unwritten Tales, The Whispered World, A New Beginning, Edna & Harvey: The Breakout, Sam & Max Seasons One/Two, Strong Bad episodes, Ankh series, Jack Keane, Wallace & Gromit episodes, Penumbra series, Secret Files series, Runaway series, Sherlock Holmes games, Dracula games, Agatha Christie games, Jane Jensen's Gray Matter, Black Mirror 2, Memento Mori 2 and so on.
There were and are lots of new and old Western & some Eastern IPs, remakes, fan games (Broken Sword 2.5, AGD's King's Quest I+II and Quest for Glory II remakes), PC to console/handheld ports in this genre during the past years and in the future. One example: After the announcment of Tales of Monkey Island, Telltales are already thinking about a possible new Maniac Mansion/Day of Tentacle game. No, this genre is not dead at all despite being buried since years on numerous internet forums (even after LucsArts' surprising resurrection).
Other mentions of "dying" genres in this thread which i think are alive and kicking: JRPGs, SRPGs, RTS.
Maybe we can agree that lots of the mentioned genres are not as nearly as successful as they used to be, but none of them are in fact dying.
