The more I look at the concept the more I'm bummed by how small it appears, spent a bit of time finding the concept arts for their other parks and this honestly looks to be the smallest at this stage, it's closer to the kids universal kids park concept art in size than it is to say Beijing, which just by building count alone had a couple of extra E-ticket size buildings in it's
original concept, then it's 2nd more detailed concept made a couple of them even larger, you would have to erase the entire kung-fu panda area and Hogwarts and a couple of minor attractions to get it down to UK size.
The footprint itself isn't the issue, but it has a lot of empty space (obviously for future expansion!) in that footprint which makes it comparatively look bigger than it really is on paper.
Really hope the rumoured LOTR area will fill one of the expansion slots rather than say, the Shrek area, which already seems too small to house an e-ticket.
I've also heard rumours that the mainstreet is where the shops and dining will be, hope this is just wrong and there is a whole separate city-walk area that's not featured yet.
Edit: crude mock showing the above, based on perspective correction and matching the size of the minion area
