What is "Gears of War: Exile"? At the moment, it doesn't represent much more than a handful of trademark listings on the US Patent and Trademark office website (spotted by Siliconera). The filings link Exile to "video game software," a "series of computer game hint books and instruction manuals," and/or "t-shirts."
Two logos (one seen above) were registered and associated with each of the aforementioned items (game software, hint books, etc.) -- perhaps something to do with that canned VGA announcement? Epic Games told us "We have no news to share," so don't expect to hear a full answer until there's an official announcement.
