Im sure it helps, but I don't think Bomberman alone is something companies are looking at.
"MR PRESIDENT. WE MUST MAKE GAMES ON NINTENDO SWITCH. BOMBERMAN SOLD HALF A MILLION." Sadly, I don't think Board meetings will be talking too much about gold old Bomberman.
What I think is going to have the most impact is 1)System sales and 2)How easy it is to develop/port and 3) How well they think their games will do. The first two are standard for any console to get some kind of success with developers. The third is a little tricky. Some genres will get brought over and other wont. The Wii had plenty of party style games because those sold. It didn't get many shooters because they didn't sell. It's also why XBox never had a problem getting shooters.
The idea that Nintendo doesn't get third party support was, partly, born out of the Wii era. The Wii was so different that developers didn't want to make games (even refusing to quit if they had to work on a Wii game). But Nintendo has often gotten third party suppose. The SNES always had games. Nintendo's handhelds got lots of third party support. The DS and 3DS and full of Japanese games. Heck, even the Gamecube had third party support. So the conventional wisdom of "Nintendo doesn't get third party suppose" is looking at a limited view of history.
Where I see Bomberman affecting is Konami. It will reassure them that their old games can still sell well. Maybe we'll get Contra or Castlevania. I think it's a real possibility now.
