Hubble Space Telescope imaging programs, from the early WF/PC era of the Medium Deep Survey, through the Hubble Deep Fields and into the ACS era of very large Legacy Science Programs, have revealed the morphological richness and strong evolution of the high redshift galaxy population. Many of these HST programs have also served as catalysts for follow-up with other facilities on the ground and in space, contributing to a new era of coordinated, multiwavelength deep surveys. However, with the important exception of small sky areas imaged by NICMOS, most of the HST work on galaxy evolution has been done with optical imaging. Therefore, our morphological portrait of the universe at z > 1 is mainly painted at rest-frame ultraviolet wavelengths. The WFC3 infrared channel will revolutionize HST deep imaging surveys, offering the opportunity for an extensive view of the rest-frame optical light from galaxies at 1 < z < 3, and potentially opening the discovery space for galaxies at z > 6. HST/WFC3 will be a critical pathfinder toward science with JWST, and it is vital that the community use this opportunity well. I will discuss current scientific issues where deep WFC3/IR imaging can make an important contribution, and consider opportunities for enhanced blue/UV imaging from WFC3, as well as optical imaging with a refurbished ACS.
