Personally, I have no hope.
Well... I want it, but I don't believe in the possibility now.
For many reasons, including Konami being Konami. Unlike Capcom, SEGA and Nintendo. Konami barely makes games anymore, it's all mobile and pachislot, which has never been a problem for me, until they started to do only those.
I want to believe that it would happen, but I'm not sure.
Sonic was always alive, it's just that Sonic Mania is a praised game, but that doesn't mean the other games don't exist (and Sonic Team wasn't involved on it, so... unless SEGA makes Mania Team a thing, not sure if that means much).
Capcom and Nintendo have quite a more hopeful side to their series.
Look at Street Fighter now, it's alive and well.
Not so much after 1999 until about 2008.
If you ask enough and support the series, they eventually try to revive it, so I was expecting Rockman 11 to be a thing someday. (and even 9 and 10 were technically a revival of the classic series, that had it last game on the Super Famicom in 1998)
And with Metroid, again... the Nintendo 64 had no Metroid, but then in 2001 the series returned.
Series sometimes go in a hiatus.
