Damn, being away from the Internet for several days is enough to lose track of everything.
But I'm just gonna say that if the Hooded Man turns out to be Bardock then I'm all for it. As "I threw away such concept as my name" would also give him a new layer to develop just as it would do for Goku. It would be an all-new Bardock, one that can even and seemingly relegate his Saiyan connections.
Dragon Ball Heroes has no history of giving a character someone else's technique, so the Hooded Man having the Full Charge Rebellion Edge can only mean one thing (I won't rule out the possibility of someone other than Bardock having it, though. I never even imagined Heroes would give a sword based technique for Bardock, yet here we are...).
And if it's really Bardock, please let this be one great family reunion between him and Goku never seen before, not like what has always been done in what-if scenarios in videogames. I'd like a decent conversation, and at least something more than just a "hint" that makes Goku realize that that man is his father.
I'll try to come back as soon as possible and keep up with the news.
Loved these two cards, by the way:
