From what I've been reading, the publisher has finaly relented and done a second production run. I've seen at least one other retailer listing copies for sale, so it can't be coincidence that there are copies out there to buy.
For anyone planning on buying to capitalise on the rarity and hence inflated price on ebay, that may be worth bearing in mind....
(For once, it's actually cheaper to buy it from Games on Demand - albeit you can't then sell it on, of course....)
I had assumed it was a reprint but didnt notice anyone else selling it. Mind you didnt have a proper look around. Makes sense with Graces F and Xillia coming out to reprint it though. I realise its more expensive but id rather have a disc copy for the sake of a few quid.
