A new town will be made available at The Sims 3 Store in the autumn (fall), called Barnacle Bay:
An island nestled in the Simuyan Sea, Barnacle Bay is a vibrant vacation getaway with stunning beaches, campgrounds, parks, and a curiously modern downtown. First settled by pirates, fisherman and artists — the world’s inhabitants now enjoy relaxing at Smuggler’s Beach and letting loose at The Wanderer’s Watering Hole. Will your trip be a vacation or a staycation?
The “curiously modern downtown” suggests it’ll be released after Late Night to include that expansion’s features. It’s not yet known how many SimPoints it’ll cost, but probably a lot!
