What's the story?There is a belief that WWE has many of their storylines planned months in advance, but according to a report by WrestleVotes, SummerSlam could be changed in order to fit in with Paul Heyman and Eric Bischoff's visions for their brands.Was told recently that anything WWE had planned for SummerSlam in advance was all subject to change once Bischoff & Heyman fully start their roles this upcoming week. Good on Vince & Co to allow a legitimate clean start. No forced agendas off the jump. That’s how it should be.— WrestleVotes (@WrestleVotes) July 11, 2019In case you didn't know...WWE appointed Paul Heyman and Eric Bischoff as Executive Directors of Monday Night Raw and SmackDown Live a few weeks ago and even though both men are yet to take over their respective brands, there are obviously plans in place for when the two stars make their moves official.Monday Night Raw has already shown signs of improvement over the past few weeks whilst Heyman has been helping Vince McMahon to call the shots, which is a good sign of things to come.The heart of the matterAccording to a report by WrestleVotes, all of the plans for SummerSlam right now are subject to change. This means that when Paul Heyman and Eric Bischoff actually take over their roles on Raw and SmackDown this upcoming week, they can make any necessary changes needed to next month's show.Whilst it's great that Vince McMahon is being open-minded by allowing this to be booked so late, it's quite worrying since there is only a month left until The Biggest Party of the Summer and that may not be enough time to build believable feuds.What's next?SummerSlam takes place live from The Scotiabank Arena in Toronto, Canada on August 11th, but ahead of The Biggest Party of the Summer, WWE has Extreme Rules this weekend which is expected to plant some seeds heading into next month's show.Do you think a month is enough time to promote SummerSlam?
