Too high of an estimate for the Corolla. The Insight numbers are pretty normal for the average inefficient, maniac American driver.

Toyota hybrids strive to get good efficiency regardless of driving style, meaning that it's hard to get bad mileage, and hard to get really good mileage. Honda hybrids leave the mileage in the driver's hands - drive it like a maniac and you'll get poor MPG, or drive it conservatively and you'll easily beat the EPA standards.

I've seen MPG in the new Insight vary between 38 and 69 in the Insight facebook groups I'm in. The new Prius or similar hybrid (Corolla) won't have that large of a range, most likely somewhere between upper 40s and mid 50s.
