Think like that, since we're in a month a little slow on new games it's the perfect opportunity to buy it, because later you won't even remember it.
August isn't exactly lacking either though, with Ys Seven out in a little over two weeks then Metroid: Other M at the very end. Then there's Scott Pilgrim and the XBLA Castlevania game on the downloadable side, though I'm waiting to see what people say on the latter. July's arguably drier, only the sheer amount of time you can sink into DQIX counterbalances that.
Infinite Space is something that interested me mostly because it's a sci-fi RPG on the DS, one that focuses on space ships more than traditional character romps, but there's no shortage of RPGs on the DS and the combat criticisms, namely being slow, leave me hesitant.
