I personally hope they're making the sign less.. noticeable. As great as it was, ithe neon red/blue text just didn't look great next to the Hogsmeade arch (but that's mostly me being picky).
Great photos, by the way! Looks like they're making a backstage portal between Springfield and Hogsmeade. It also seems like Android's doesn't have a roof because the side of it that we see in that first photo is essentially just a wrap-around wall, which could mean another potential restroom location or another team member entry.
By the time Springfield is officially open, we may just see walls pushed back to stand just in front of the Hogsmeade arch.
