i'll be speaking in terms of games i'd buy.
valkyria chronicles
echochrome
fat princess (although here i'd actually prefer a sequel)
beyond
rachet and clank(s) (the reimaginantion looks perfect though so more of that would be great)
puppeteer
more pixal junk games
i also think gravity rush 1 will get ported along side a ps4 announcement of gravity rush 2.
