Do you think FFXIII success can raise sales for previous jRPG?

No.

Other JPRG's may be better than FFXIII but people being stupid like they are will still say well FFXIII looks better so it must be better.

Other non-SE JRPG's just can't match SE's advertising budget and graphics quality so they're really just killing the genre bit by bit on consoles.
