Yeah i know exactly what you mean.
I have had the same feeling for Persona 5 for almost five years now. Just recently their developers bought the rights to a website under the name persona5 so that just made me even more excited for it!
As for Drakengaurd 3 that's awesome news, I loved the RPG's from the PS2 era. I get really excited when publishers choose to continue/revive obscure niche games such as this one.
