I'm not sure palying new suits at the 3-level are game forcing in competitive auctions is standard - but it's certainly standard they have extras. (Its just my preference to play them as 99% forcing).
In non-competitive auctions...new suits at the 3-level are always game forcing... in the auction shown 1h-pass-2d-pass-3c promises extras (15+) in sayc - it depends which style of 2/1 you are playing whether a high-level reverse promises extras.
