That's generally unlikely. Even other creators that announced a localized version ahead of their JPN release still didn't release the localization along side the primary game.
This author however has not yet, for what I can tell, formally announced any localization though. But going off history, likelihood of it happening is high (and likely going to be Kagura).
Sold >20K already though. Still seems to be going strong, after all ... only been released for like a day and the thing sold thousands in hours. Guess he had a lot of eager fans (going by eroge standards anyway).
Though that also meant it ended up on pirate site feeds in a matter of minutes.
