  Building on the great success of the LISA Pathfinder mission, the outlines of
a new LISA mission design were laid out at the $11^{\rm th}$ International LISA
Symposium in Zurich. The revised design calls for three identical spacecraft
forming an equilateral triangle with 2.5 million kilometer sides, and two laser
links per side delivering full polarization sensitivity. With the demonstrated
Pathfinder performance for the disturbance reduction system, and a well studied
design for the laser metrology, it is anticipated that the new mission will
have a sensitivity very close to the original LISA design. This implies that
the mid-band performance, between 0.5 mHz and 3 mHz, will be limited by
unresolved signals from compact binaries in our galaxy. Here we use the new
LISA design to compute updated estimates for the galactic confusion noise, the
number of resolvable galactic binaries, and the accuracy to which key
parameters of these systems can be measured.
