We present simulations of quasar colors, magnitudes, and numbers at redshifts56 epoch takingadvantage of the new UKIDSS near-infrared filter set, and we examine theredshift intervals of maximum productivity, discussing color selection andsurvey depth issues. On the basis of the SDSS sample, we find that the surfacedensity of z>4.7 quasars increases by a factor of 3X by extending 0.7i-magnitudes deeper than the SDSS spectroscopic survey limit of i=20.2 --correspondingly we predict a total of ~400 faint quasars in the SDSS main areathat have redshift z>4.7 and magnitudes $<20.9.Comment: 14 pages, 11 Postscript figures, uses emulateapj.sty The Astronomical Journal, accepted, in pres
