Clavia may re-manufacture expansion boards for the G2. However Clavia needs enough people to commit for them to go ahead with it. A discussion has been started at the Electro-Music forums for people to say if they want one.
This is what the Electro-Music post states:
"Clavia reacted possitively on the request to make a new run of the G2 expansion boards. There are some restrictions though:
1 Clavia wants to sell at least 50 expansion boards to make it profit able.
2 All the components have to be available still
3 Clavia doesn't sell to private costumers, so there has to be a kind of distributor
4 The price isn't set yet"
