Legacy Battlefield games fight through GameSpy shut down according to a Tweet from the Origin Twitter account.
@Tofugames We’re working on transitioning those games after the shut down so you’ll still be able to play them.

This means that previous Battlefield titles that used GameSpy will still be playable after the shut down on the 31st May. This includes Battlefield 2, Battlefield 2142 and Battlefield Bad Company 2.
This adds Electronic Arts to the list of other publishers Bohemia Interactive, Epic Games, and Activision which have all announced at least partial solutions, the biggest publisher still keeping quiet is 2K, which used GameSpy for Borderlands.
