There are sources on the Internet - including a website named Generalmusic and a Wikipedia entry - which state that GEM, LEM and ELKA products will be manufactured again in 2015, including re-releases and completely new models! The company has obviously been purchased by a Finish investor, and production is said to be set up in Finland.
