I thing its pretty obvious that these guys knows that their fans are growing old and visual kei is at the last breath so they will grab some coins while they can. And not just them, a lot of the old guys are active to grab what they can while they can, shit, even deadman has returned.
I wound also like to hint that I think the reason why Yoshiki never released the new X JAPAN album is because he can’t, probably this guy fucked a contract with some label, management or someone who put some money in it and they are on some kind of litigation.
