I know some of the Ikelite 350D users have reported that the new Canon 10mp 400D/Rebel Xti/Kiss X doesn't fit the Ikelite 350D housing. I was a bit surprised considering that the dimensions of the new 400D are almost identical to the 350D barring 1mm around the grip... Anyways, I liked what I was reading about the 400D, especially about the new autofocusing which it borrows from its big brother the 30D, the bigger 2.5" LCD screen, and also the larger buffer. While the new dust cleaning sensor doohickie is nice, I'm not sure existing 350D users will really miss this feature... 10mp sounds nice but it isn't that much of a leap from 8mp and will just takes up more room on your flash cards... But for me it was worthwhile considering the 400D as I was looking to get a backup 2nd body.
Anyways, my camera shop was nice enough to allow me to try one of their demo 400D's in my S&S 350D housing. The housing tray adapter fits nicely on the 400D body and the body slides perfectly into the housing. All the critical buttons match up without any modifications - the shutter, aperture, mode dial, main dial, AE/FE lock button, AF point selector, all arrow buttons and selector buttons. Unfortunately the buttons on far left side of the 400D - display, menu, jump, playback, and delete buttons are just left of the existing buttons to accomodate the 400D's larger 2 1/2" LCD. So basically all the critical controls you would need u/w work straight off the bat.
The remaining buttons left of the LCD are just slighly offline from the 400D. I think with some plastic and a dremel tool, I could make some L shape feet for these button plungers so I can access the display, menu, playback, delete, AND the drive buttons. Worse comes to worse, it's still a very workable housing without access to those buttons. Maybe set the preview setting to a longer display time. You need to disable the display-off sensor on the menu so that the display shows up all the time except when you take a picture and it shows the preview. Otherwise the rear housing will force the sensor to keep the display off.
Now the nice thing about the 400D is that the entire LCD now acts as the setting screen that was separate on the 350D. So you get this nice bright 2 1/2" LCD showing you all your settings (av/tv/iso,metering!,AF mode,AF point selection, WB, drive mode, and many more other indicators). So you could do a lot of presetting without putting your eye on viewfinder or straining to see the old display (BIG bonus for nite dives).** on hindsight, the bright status display on the LCD might be distracting at night when using the viewfinder...
Anyways, here's how the 400D looks in my S&S 350D housing and also how the display looks from outside the housing. The ENTIRE 2 1/2" LCD is viewable from the rear of the screen.
fits like a glove... Canon 400D in a Sea & Sea 350D housing

this big status display is gonna be nice on nite dives!!!

I also tested my S&S TTL Converter w/ my Inon Z-240 and there doesn't appear to be any compatibility issues!! And no issues with the viewfinder or existing S&S focus rings (60mm and 10-22mm) as expected.
I wouldn't be surprised if Sea & Sea does come out with a modified rear housing mold with all the button in the right place for the 400D or even some button modification kit for existing 350D users.
