The Egyptian civilization lasted for thousands of years from the pre-dynastic period (5500 B.C.E) to The Roman Period (30 B.C.E-~300 C.E). (1) There is a wealth of information still to be discovered. There are archaeologists in the deserts now still making discoveries. There are several academic journals on the subject of Egyptian Archaeology and if you have access to JSTOR, I'd recommend you check them out. If you would like to keep up with archaeological discoveries, I'd suggest checking out this site (http://www.archaeologica.org/NewsPage.htm) With any type of archaeology, there is always more to find even when those findings are simply more pottery sherds.
