Interferometry with several telescopes in a phased array of several hundred meters baselines should easily and routinely deliver spatial resolutions in excess of 1 milliarcsec and visibility precisions of better than 0.1 percent. On the ground, the effect of atmospheric turbulence currently limits practical operations with large telescopes to the near and mid infrared where limiting K magnitudes of 15-20 can be reached in principle. In this presentation, I will describe and compare the expected performance and scientific capabilities of the current generation of interferometric IR arrays employing very large telescopes including the LBT, Keck and VLTI facilities that are expected to be operational in the next few years. These facilities should finally establish interferometry in its rightful place as a valid and important astronomical tool as many and exciting new, scientifically compelling results will surely follow. Arrays of kilometric ground and space baselines should provide another substantial leap forward in the not-too-distant future in our ability to survey the local universe at even greater spatial resolutions.
