Thorpe often have a bolt on attraction/update for their new coasters to keep the GP interested. Stealth got the 'version 1.1 update now faster etc' update, Saw got the maze and Swarm has got this backwards rows and extra theming. I'd much rather this than the rumored Vengeance ride as a bolt on Swarm attraction.
They have also hinted at more to be announced for the park, now this could be quite literally anything but there is a strong rumour of the No Way Out refurb which I strongly believe will happen. If they keep this up and update rides/areas each year (which I believe they could do as there aren't many flat rides/bolt on attractions that could be introduced now) then the park will start to look very very good.
