Thanks.

Are there any other signature algorithms or schemes that are likely to 
appear within the next few years in either OpenPGP or GnuPG?

Right now, my understanding is that RSA, DSA, ECDSA, and EdDSA are the 
only signing keys / algorithms. Is this correct?

I only have specifications for RSA and DSA keys in the current proposal, 
but I think there is no issue augmenting the proposal to support ECDSA 
and EdDSA keys. If there other types of signing keys that are likely to 
appear, I would like to take a look to see whether they can be included 
successfully in the proposed ring signature scheme.
