Apparently Clubskill.com (UK-based) got a, "leaked magazine article that details some of the upcoming content on the Xbox Live Marketplace." If you browse to the link above, they show a scan of the article. Notable information in the article includes:
$15 for Lumines Live? I am not sure I would pay that since I already own the game for my PSP. If they add some cool multiplayer modes I might go for it. Street Fighter II for $5? For me that is a no brainer, I gotta have it.One of the noteworthy downloads featured is the much anticipated (and strangely punctuated) Street Fighter II' Hyper Fighting, which the scan says will hit Marketplace in June for 400 points ($5). The game's release date has been in question for some time now, since it missed its initial "early 2006" date.
Other highlights from the scan include a few new modes for Project Gotham Racing 3 ("Cat and Mouse" and "Proximity Based Racing"), a hardcore package for Kameo featuring a new difficulty level for single and cooperative play, and Lumines Live in August/September for *gulp* 1200 points ($15). However, some of the content has already been released, indicating that the scan is dated.
