Can't really confirm anything until QA is all set. There will probably be 2 releases per platform per month (if a game is PS4 exclusive, it will be posted along with a Vita exclusive - for example Lost Sea will lauch alongside Soldner X-2). I don't think any of our Summer games will be over $24.99, but we have a tentative August release that may end up at $34.99.
We're also really close to sealing a deal to make those Atelier games a reality.

No idea on a date for those as no final deal is set. They're going to be a big expense for us so we'll need everyone's help spreading the word if/when they go on sale. We're pushing hard for these because the demand was clear.
