I've already preordered Atelier Iris 3 (and was not amused that my credit card was charged at the time of the pre-order... but anyway) and got the artbook and soundtrack (two CDs, woot, maybe it'll be a NA pressing of the Japanese one?)
I'll probably purchase Dawn of Mana near the release date, but for some reason, it's getting more and more difficult to drop 49.99 on a PS2 title.
For me, the question of whether or not a game will be played has never been an issue. I know 99% of the time the games will just sit on the shelf until I reach boredom of mass proportions (which ain't happenin' with a fulltime job), so I guess I've come to terms with the fact that I'm an obsessive collector, though not as much lately.
I suppose I'll eventually own all of these RPGs, but I'll most likely be waiting for price drops for all of them.
The latest market trends have been inspiring; I can't name a single PS2 RPG that's commanding over retail price right now... that was released in the last year, anyway, and definitely not a single PSP one. (I still need to pick up a copy of Blade Dancer, however hideous it is.)
DS games seem to lead as far as the current "zomg rare" trends are concerned. Hopefully the publishers will learn from this and learn to judge the games' audiences better (considering future series releases, for example - Wario Ware: Touched comes to mind... the demand went way up after the Wii title came out, I think.)
