Statistical observations of the epoch of reionization (EOR) power spectrumprovide a rich data set for understanding the transition from the cosmic "darkages" to the ionized universe we see today. EOR observations have become anactive area of experimental cosmology, and three first generationobservatories--MWA, PAST, and LOFAR--are currently under development. In thispaper we provide the first quantitative calculation of the three dimensionalpower spectrum sensitivity, incorporating the design parameters of a plannedarray. This calculation is then used to explore the constraints these firstgeneration observations can place on the EOR power spectrum. The resultsdemonstrate the potential of upcoming power spectrum observations to constraintheories of structure formation and reionization.Comment: 7 pages with 5 figures. Submitted to Ap
