Is the upcoming Dragons Gate MK or MKD?

I believe its MKD

poop. but can you still use the new SA's for Mage Knight?

I'm not sure

I would assume that there will be rebellion versions of the SAs (or they will be the same in rebeliion). Otherwise the figures wouldn't be viable in rebellion, because they have extra cost on them that pay for an ability you can't even use.

Get a life MartL... I reported you.
