I don't think it means more to Nintendo..but it means more to third parties. Especially, Japanese third party companies.
SEGA, Platinum, Atlus Ltd, Bandai Namco Entertainment, Capcom, and Square have a lot of games from them that are previous and/or new. Imagine if this is the year that Japanese companies come in like a lion; and support the console/handheld in a big way.
It'd make sense, especially as the Switch continues being a hit in Japan.
..The big question to me, lies with Atlus. And more specifically, would they want to get Shin Megami Tensei V as fast as possible, or hold it off and do a Persona 4: Golden on Persona 5 (with what I assume being called: Persona 5 Reunion).
