There are many good points in these posts......for all kinds of reasons......
A common theme is that the Canon housing is good enough for now and has limitations......
So why buy it? Just to replace it later.........
I went down this road with a G9 and Canon housing........
I did go with the S90 over the G11 due to the housing cost and smaller overall size....
The G11 is capable of pro level underwater pictures not the blue/green colorless pictures that many end up with.........my sense is the OP can keep and use the G11 for many many years..........
I did preface my comment that budget would allow it.....
If the OP wants to get really get into underwater photography and be able to get the "shot" not just get lucky ever once in a while then buying a full rig is the only way to go......
While the learning curve is steep, it is not impossible.....
Buy the housing that can grow with you, not limit you, learn to use it correctly (this includes how you dive, buoyancy control, etc) and add capability to your rig as you can afford it.......
The first 5 shots below are S90/Ike Housing/WA lens and no strobe......
I think the key to the pictures is the WA lens as it allows you to get "stuff" in the frame.....
I went B&W in 4 and 5 as there was not enough light at depth...
1,2 and 3 were taken in shallow water on bright days........
The 6th shot is the G9 in the Canon housing with a strobe - good color, detail, etc....but not enough FOV to get the full turtle and get color/detail, etc......
Just my thoughts........
