The BoRG survey, a large-area optical/near-IR HST program aimed at finding the most luminous z 8 galaxies, also enables the investigation of galaxy properties at z 2. Similarly to the z 8 case, the pure-parallel nature of the BoRG survey allows us to study these galaxies without being biased by cosmic variance, which affects surveys resorting to a single or a few fields. We present the typical number counts of the active and passive samples at z 2, determined using a Y-H vs. V-Y color-color selection. We discuss their clustering properties and preliminary measurements in terms of galaxy sizes and surface brightness profiles. With upcoming multi-object spectrographs such as MOSFIRE on Keck, it will be possible to derive internal kinematics and spectroscopic redshifts for a large sample of z 2 elliptical galaxies while carrying out at the same time spectroscopic confirmation of z 8 candidates.
