The newly announced Nauticam NA-D7000 is an underwater housing for the Nikon D7000, which allows you to take the 16MP DSLR down to a depth of 100M.  It will set you back a bit on top of the D7000 sticker price though.  The Nauticam NA-D7000 carries a retail price tag of $3100 and should be available at the end of this month (just in time to make it on your wish list).
