I'm expecting a new build to be used in the preview later this week, since they've announced this one a month in advance, and it's about time for the announcement of a new zone. Edit: Since this might be my last chance , I might as well give my zone predictions, which I've been thinking about over the last eight months. Since we still don't know how many zones are going to be in the game, I'm assuming a range of five to ten remixed zones. Sonic 1: There's no way we'll see Marble or Labyrinth, since the amount of new content required to make them Mania-quality would be better spent on a whole new zone (which is kind of what Hydrocity and Marble Garden are, to a degree). Spring Yard would be a good pick, but with the CPU/COPE in Studiopolis and Roller badnik in Mirage Saloon, it doesn't seem like it's going to happen (which is a shame, because it's one of my least favourite zones of the classic games and I'd like to see it done right). Star Light seems the most likely, until you remember how much everyone loves Stardust Speedway (including me). Ultimately I think Scrap Brain is the most likely, as the devs have plenty of elements from later games to draw from in remaking it. That said, unless they're going all-out and including two zones from each game, Green Hill will probably be the only one. Sonic 2: Chemical Plant would be the obvious pick were it not for Generations, and I don't think even SEGA are willing to risk using it again (I wonder if the devs or SEGA got to pick the levels?) Aquatic Ruin would be a good choice, it's a level with lots of room for expansion, but it might be a bit too similar to the new Green Hill. Casino Night has been done to death, especially by Sonic 4 and Generations 3DS in quick succession. Hill Top, Oil Ocean and Metropolis are all kind of 'eh'. Wing Fortress would be a contender were it not for Sonic 4 ruining it. Thus, Mystic Cave is easily the most likely zone to be in Mania, to the point of saying I'm 99% sure of it. It's got a unique theme, great design, lots of potential and fantastic music. Sonic CD: Most of SCD's zones (mneh) are already 'remixes' of Sonic 1 zones, which makes things a bit hard. I don't see Palmtree Panic, Tidal Tempest or Metallic Madness being used. Collision Chaos would be interesting, but we already have a lot of the game's 'bounce' quotient covered between Studiopolis and Mirage Saloon. Wacky Workbench is probably out because everyone except me hates it. Quartz Quadrant is the most original level theme in CD, so I think it's the most likely to make an appearance, though I would personally prefer Stardust Speedway. I want to speed through a maze of overlapping, layered roads, but without CD's consistent clunk. Ideally, we'll get both QQ and SS. Sonic 3 & Knuckles: I think this is where the most interesting remixes will come from, and it's much harder to pick zones than the other games. Angel Island is too similar to Green Hill to make an appearance. Mushroom Hill was in Sonic Generations 3DS and Sky Sanctuary was in Generations Proper so I don't see them appearing again. We know Sandopolis won't appear because of Mirage Saloon. Marble Garden was great, but I think it exhausted its potential the first time. The zone I most want from Sonic 3 is Hydrocity, and the zone I most want from S&K is Lava Reef, but there are lots of other contenders. Flying Battery and Death Egg presumably crashed somewhere and are now overgrown wreckage. Ice Cap could certainly benefit from an overhaul, and it's near-universally loved. Carnival Night and Launch Base are both excellent zones in their own right. I guess the most likely four are Hydrocity, Ice Cap, Flying Battery and Lava Reef? Though I won't be surprised if the plot involves the Death Egg somehow.
