I noticed Catherine has been lowered to $20 for July, however I've also noticed many Atlus games have been free or gone on sale really cheap for Playstation Plus memebers over the past few months. Anyone know if there is a cycle or a way to tell if Catherine will be going on sale for Plus memebers? I don't want to buy it then it's free next month or cheaper then the current price.
Lest Sony announces something in the PlayStation Blog (and subsequently on other news sources), there's no telling when or if the game will be free or on sale to Plus members.
If I'm not mistaken, there was a sale on Catherine for Plus some months ago. However, that was a discount (in the $20-40ish range) rather than a giveaway like you're expecting.
