Well except in that episode Duncan had only heard vague rumors of one and had to ask Joe, who'd also only heard rumors, so first-hand knowledge is a retcon. Endgame should maybe be disregarded too, as they forgot he was never married and was cursed not to be.
All I could find online of the new series is that #1 is supposed to be out but doesn't seem to have been scanned and isn't available digitally (which for my purposes means it doesn't exist). The Emerald comics website has a variant cover of it for the low low price of fifty bucks and a free sampler with an excerpt, the latter, however is a dead link. There was enough in the two reviews I found to suggest it's awful though - for some reason his hair is grey and he's living on a colony on Venus after having fought in the second Martian war for independence.
