That's according to the Japanese business paper Nikkei (via Dr. Serkan Toto), which reports this week that all the chatter about Nintendo branching out to mobile platforms is about to culminate in an announcement that will take place on Thursday.
Late in 2013 Nintendo executives revealed that the Mario maker was "experimenting" with smartphones and tablets, though it will likely never publish full Nintendo games on mobile platforms. But Nintendo of America President Reggie Fils-Aime said Nintendo was considering launching apps and smaller games that would aim to drive consumers to Nintendo's hardware.
It's no secret that Nintendo hasn't been doing so hot lately, and this currently hypothetical initiative seems like exactly the kind of thing it might try. I'll be keeping an eye out on Thursday for any announcements.
