Launch, or announce? Everyone else has been saying ~April 8-9 for the launch.
I saw about 50% for the graphics, and CPU performance gain varies - if it clocks higher, *maybe* 20% for desktops, perhaps 15% is more realistic. For mobile quads, ~20%, maybe more; for all dual-cores - IPC gain, ~200mhz higher clocks, that's about it; and for 17W dual-cores, a pretty big jump (>20% if you count turbo boost).
There's already some benchmarks of the laptop i7-3920XM out, that do show the ~50% faster graphics. http://forum.notebookreview.com/hardware-components-aftermarket-upgrades/636978-ivy-bridge-mobile-3920xm-tested.html
