The announcements at MWC about Ovi Store included the revelation that N-Gage games would be distributed through it. Although this hasn't actually happened yet, N-Gage demo icons have started appearing in the Ovi Store website's "related content" sections for some games. (Clicking on them leads to a message saying they're not available, so perhaps they're in a pipeline still waiting for approval to go live.) See below for a screenshot.
