The Home and Garden Expo, one of the larger events of the Relay for Life in Second Life, is taking place in several temporary sims south of American Cancer Society. But the one getting the most attention is the Linden Homes Preview sim as like the name suggests, people can check up on what the soon to be available set of Linden Homes look like.
Not all of the Linden Homes will be on dry land. Some will be houseboats parked at docks.
According to Inara Pey and Daniel Voyager, what was assumed about the SSP continent is true. It will be the location of the new Linden homes. It's opening is described as "weeks" away. The plan is to rename it "Bellisseria" and place it between two other continents to form a larger mass of contiguous sims that one can walk/fly/drive from one end to another without the need for teleports.
As with the other Linden Homes, these are available only to Premium Residents, and obtaining them will be done via a webpage. As the new Linden Homes are occupied, the smaller landmasses where the older ones are will be dismantled once they're empty of residents.
