Fermi is certainly one heck of a headline stealer. Despite the fact that Nvidia has announced the launch date and the cards' names, there is still plenty of information to write about this particular card.

The recent development is that the card might launch on the 26th in the USA and 27th in Europe  mainly due to the 9 hours time difference between California (Pacific time PT) and Central Europe time (CET). At this time, they should remain the launch date but of course it can be pushed.

Now for the fun part, the world-wide availability of Fermi based Geforce GTX 480 and 470 is most likely to happen on the April 6th, due to some logistical issues. The final cards are ready and benchmarkers are getting them as we speak, but it takes some time to manufacture the cards and fly them from China to Europe and US and get them in shops. This might be the cause of the availability delay from 27th of March to April 6th.

As this is all under heavy discussion and it tends to change daily, there will probably be some more changes before 26th.
