I agree with what's been said really - a new flat of some sort on Slammer's site would be great.
A dark ride to replace the stupid Ghost Train would be good too. I understand the shop in there (which is brand new) is now empty? I wonder if it's flopping (again)...
Ghost Train replacement might be on the cards at some point?
I guess it depends on how the numbers look when Hyperia opens. Coasters really are the crowd-pleasers for Thorpe, so maybe another coaster in the next 4 years? There's plenty of space for one over on the very expensive bit of land they created behind Stealth ages ago!
However, what I'd REALLY like to see!
Personally, in the longer-term, I'd like to see Walking Dead and the entire pyramid building disappear, along with Slammer, the megastore and Storm Surge. That would clear a lot of tacky dated crap from the centre of the park, for a pretty big ride and central area there.
I think it would make a nice central plaza with either a coaster or a big water ride, with shops/restaurants.
Whatever happens, I think we will see some serious investment across Merlin over the next few years if Universal gets the go ahead.
They're already investing heavily in Thorpe (finally) with all the sparkle improvements and Hyperia. With the new brand they've also promised a vibrant new future, so hopefully this is a sign of great things to come.
