TL:DR, delete your safe files and start over without cheats.

No there isn't. the newest one from the series is "Valkyrie Profile the Accused One" for Nintendo DS and it must not considered to be "Valkyrie Profile 3". Tri-Ace isn't as large as Square-Enix so their development capability is limited because of limited Human resources hence they can focus at their 2 or 3 games project at a time as far as I know they are at their full capability already right now. But After Valkyrie Profile 2 Silmeria hit the market it was performed and sells well (I am also loved it! Playing it 'till death and it stills fun!!) and if you ask me, I'd answer there is a high possibility for Tri-Ace creating Valkyrie Profile 3 in the future...so be patient pal. ^^Cheers!

Valkyrie Profile happened in 1999.
