As of the latest information available, the Yamaha FG3 is expected to be available in the United States by the end of 2023. This estimate is based on the typical timeline for Yamaha guitar releases, which often occur in the late fall or early winter. The FG3 is a highly anticipated update to the popular FG series, and its release has been eagerly awaited by guitar enthusiasts.

The reason for the expected release date lies in Yamaha's historical pattern of product launches. Yamaha has a reputation for planning and executing product releases with precision, typically releasing new models in the same time frame each year. According to data from Yamaha's official press releases and industry analysts, the FG series has historically been updated every two to three years. The last major update to the FG series was in 2021 with the FG800, which suggests that the FG3 would follow a similar release schedule.

Furthermore, the demand for the FG series has been consistently strong, with the FG800 selling out quickly upon its release. This high demand, coupled with the anticipation for a new model, indicates that Yamaha is likely to release the FG3 in a timely manner to capitalize on consumer interest. Additionally, the guitar industry as a whole has seen a surge in demand due to the COVID-19 pandemic, with many consumers turning to hobbies such as music as a form of entertainment and stress relief. This increased demand for musical instruments has also influenced Yamaha's production and release schedules.

In conclusion, the Yamaha FG3 is expected to be available in the United States by the end of 2023, following Yamaha's typical release schedule and the strong demand for the FG series.
