That's really sad.
The day the Another Code sequel was announced as Wii retail game I already had the feeling it wasn't a good decision. I think Cinq should have either stayed on DS or switched to Wiiware with their adventure games instead. Omitting voice acting was another bad design decision.
You can't make money with classic point&click adventure games these days, if it's not a remake of a LucasArts classic or a borrowed LucasArts franchise (see Telltale).
The best European p&c adventure developers for PC, who are still making retail games, are struggling either. Some of them make better games than Telltale (especially Daedalic and Péndulo), but not many people buy them and publishers only advertise them in a few countries, if at all.
The classic adventure game genre (i.e. adventure games with an inventory) will not die, but I think it will only survive via download services.
Despite all the hopes we had with DS/Wii/PC as three possible platforms for p&c adventure games, imo this generation proved that this specific genre has no future anymore in retail.
