The next LEGO Ideas gift with purchase isn't too far away with a recent leak revealing exactly what the gift with purchase set will be. The next gift with purchase currently goes under the name 40487 'Sailboat Adventure' and will be available exclusively to LEGO in the next few weeks.
As already mentioned, the build itself is a sailboat with two big white sails. These are connected to a small wooden boat that has just enough space for two Minifigures and a few bits of fishing gear. Two different Minifigures are included with one being male and the other being female.
