Pre-Orders from Amazon for Nikon D800E got a mail saying that Nikon has delayed the release date for Nikon D800E. Proposed released date for Nikon D800E was April 12. However there's no information regarding delay of Nikon D800 which will be releasing on March 22. Still no information about new release date for D800E but Nikon has to be quick since Canon is about to release series of DSLR in coming months.
If you planned to buy Canon 5D Mark II this week, just wait a week. We got a news about price reducing of Canon EOS-5D Mark ll 21.1 MP Digital Camera on starting on March first week. We still waiting for the confirmation about what the reduction will be, but with the release of Canon 5D mark III and Canon EOS 650D Rebel T4I, definitely there will be a price drop.
Therefore one week waiting will be definitely worth the money
