The Epson Home Cinema 8700UB projector comes with a two year, parts and labor warranty. In addition, it includes Epson's replacement program for both years, which considered together, makes it a superb warranty. The similar, but more expensive Pro Cinema 9700UB comes with the same overall package, but for three years instead of two.
While two year warranties are the most common found on 1080p projectors, a few projector models offering three, and a number of lower cost, entry level models offer only one.
Among the competition, the Sanyo PLV-Z4000 has a three year warranty, while the Panasonic PT-AE4000 has one (but they usually are giving away a second limited warranty with an hour limitation). The BenQ W6000 has one year. You get the idea.
