Is there a list of upcoming yugioh cards being released in shonun jump.?

ive been searching the web and cant really find info on that. if there is no website then i'll understand. maybe some kind of sneak peak thing perhaps. reason why is because im waiting on a preorder for legal version of slifer the sky dragon so i can complete my god card deck. speaking of slifer the sky dragon, is there any information on a release for him yet haha. well thank you every one
