Amazon Japan has put up what seems to be Tales of Xillia's Original Soundtrack up for pre-orders.
The site has put up two versions: a regular one at 4,200 Yen (around $54) and a limited edition one at 5,880 Yen (around $75). The regular one consists of three CDs while the LE one will have an additional CD containing a special talk by Jude and Milla's voice actors and a set of 3 cards with DLC codes for something. Both are listed for a September 7, 2011 release, just a couple of days before the release of the game itself.
In addition, Lalabit Market just Tweeted that the cushion covers for the Tales character pillows in Tales of Cafe will be sold at this year's Tokyo Game Show. However, since it would be difficult to manufacture all of the covers available in the cafe, a poll will be put up in Facebook to determine which specific ones will be sold at TGS. No news yet on which Facebook page the poll will be in, though.
