#1 Reigns making up for lost time
Since John Cena is now focusing primary on a movie career, Roman Reigns is without a doubt the company's biggest star. It is currently unknown how long Reigns will be away from the ring, but it should be safe to say the 33-year-old will at the very least miss most of 2019.
When Reigns eventually returns, the WWE will waste no time in pushing him back towards the top of the card. Vince McMahon will have big plans for Reigns, and he is likely to quickly return to headlining the main events at major pay-per-views. Being part of The Shield again would reduce his singles push, and it is much more likely that Reigns will clash with his former teammate Seth Rollins.
When looking at all the facts, a Shield reunion cannot be completely ruled out, however it seems incredibly unlikely that we will see any reunion in the next few years. Instead, wrestling fans can be excited to see what each member could do in their individual exciting journeys in the company.
