Microsoft's recent trademark filings has lead to the anticipation of two new titles, though it's anyone's guess where they'll end up.
According to IGN, Microsoft has registered Tentacles: Enter the Mind and Iri and the Blind Forest both as game software. It is believed that an official reveal of each of these titles will soon be underway. Microsoft has recently teased that a major unveiling of its ID@Xbox titles will happen at the Game Developers Conference, which takes place from March 17 through March 21, which is where we could see these titles be officially announced.
Given the names of the titles, they are likely indie titles being developed by the ID@Xbox program. In particular, the Xbox One is in need of bolstering its position in the indie games market, which Sony is doing extremely well in by comparison.
