The telescope has been upgraded in April, 2005, to the 10 Mton scale detector NT200+. It's main physics goal is the detection of signals from high energy neutrino cascades. NT200+ reaches a 3-year sensitivity of 2 \times 10^{-7}cm^{-2}s^{-1}sr^{-1}GeV for an all-flavor diffuse cosmic E^{-2} neutrino flux for energies 10^2 TeV ÷10^5 TeV. Desgin and sensitivity of NT200+ are described. NT200+ is forming the basic building block of a future km3-scale (Gigaton-Volume) Baikal Telescope. Research and development work on that next stage detector has started.6 pages, 8 figures; presented at 2nd Workshop on Very Large Volume Neutrino Telescopes (VLVNT2), Catania, Italy, 8.-11.
