1.5-inch (18.7 x 14mm) sensor

That's a 23.4 mm diagonal, so it's not even 1 inch. It's basically in the middle of what the leak said and what's been speculated.

Okay, I see that Wikipedia says that x" have nothing to do with real inches. In fact, with a real size of 1", the marketing departments actually call this 1.5".  :o

Bottom line, Canon did not fit a 38.1 mm (1.5 real inches) sensor in a G-sized body.

There's a lot of confusion in this thread about sensor terminology. 1.5"  is NOT  1.5 inches in the standard unit length (25mm) that we're familiar with.

The whole thing is quite confusing, it would be nice if everyone would use crop factor or just publish the sensor dimensions instead.

I wholeheartedly agree.  The present designation is much too confusing to the serious photographer who wishes to make a comparison, let alone the average consumer.  It's high time for camera maunfacturers to state in clear, unambiguous language the size of their sensor, whether it's in dimensions, both width AND height (in mm) or, better yet , expressed as area [i.e.,  mm2 (squared)].

Who says they do not? All manufacturers of cameras specifically state their sensor size dimensions in millimeters.

If so, where?
Yes, the DSLRs, whether full-frame, APS-C or some other size,  nearly always state it in their specs, but I've looked pretty hard to find this for point-and-shoots, and have come up empty.  I think I'm not the only one who can't find it, as I seem to recall a column by the NYTimes' David Pogue on this very subject.
Say manufacturers, isn't it time for full disclosure?

go to www.dpreview.com, look up Articles/glossary/sensor size. You will find almost ALL sensor sizes vs "X/Y" notation.
