N2 - Telescopes to be launched over the next decade and a half, such as JWST, EUCLID, ATHENA, and Lynx, promise to revolutionize the study of the high-redshift Universe and greatly advance our understanding of the early stages of galaxy formation. We use a model that follows the evolution of the masses and spins of supermassive black holes (SMBHs) within a semi-analytic model of galaxy formation to make predictions for the active galactic nucleus luminosity function at z >= 7 in the broadband filters of JWST and EUCLID at near-infrared wavelengths, and ATHENA and Lynx at X-ray energies. The predictions of our model are relatively insensitive to the choice of seed black hole mass, except at the lowest luminosities (L-bol <10(43) erg s(-1)) and the highest redshifts (z > 10). We predict that surveys with these different telescopes will select somewhat different samples of SMBHs, with EUCLID unveiling the most massive, highest accretion rate SMBHs, Lynx the least massive, lowest accretion rate SMBHs, and JWST and ATHENA covering objects inbetween. At z = 7, we predict that typical detectable SMBHs will have masses, M-BH similar to 10(5-8) M-circle dot, and Eddington normalized mass accretion rates, (M) over dot/(M) over dot(Edd) similar to 0.6-2. The SMBHs will be hosted by galaxies of stellar mass M-star similar to 10(8-10) M-circle dot, and dark matter haloes of mass M-halo similar to 10(11-12) M-circle dot. We predict that the detectable SMBHs at z = 10 will have slightly smaller black holes, accreting at slightly higher Eddington normalized mass accretion rates, in slightly lower mass host galaxies compared to those at z = 7, and reside in haloes of mass M-halo similar to 10(10-11) M-circle dot.
