Sorry, my sarcasm meter wasn't turned on enough. I just wanted to make sure any manufacturers who read this knew that making housings reusable was something good, not bad. As you say, they probably "know" it logically but the primal cries of the marketing department wanting to sell something 'new' all the time probably drown out the knowledge.
I hadn't thought thru the U/W mode issue before, but it does make sense that they wouldn't make a housing of their own for a camera they didn't plan an U/W mode into. Fortunately the U/W modes are more or less useless outside of a thin range of conditions, so that doesn't stop the 3rd party housing manufacturers.
With the 420's LV advances it seems like the 330 is well and truly orphaned as a design approach. Not much likelihood of a 430 or 530 now it seems. Ah well, just got my kit together, got it fairly inexpensively thanks to buying used, so can't regret it too much. Besides, I've never taken a single pic yet like the scads jlyle gets with his 330, so I've got plenty of growing room with this camera still before I chase the upgrade train myself.
