EF-S 17-55mm f/2.8 IS USM
EF-S 17-85mm f/4-5.6 IS USM
EF-S 18-55mm f/3.5-5.6
EF-S 18-55mm f/3.5-5.6 USM
EF-S 18-55mm f/3.5-5.6 II
EF-S 18-55mm f/3.5-5.6 II USM
EF-S 18-55mm f/3.5-5.6 IS

Meaningless.

Once digital sensors were developed, I'm sure that all the companies from
then onwards allowed for digital sensors in the design of their lenses.
In the case of many lenses at or over, say, 70mm focal length, there may
be no need for a separate crop-frame version.

And of course every Pentax K mount lens ever made will mount on an all
Pentax D-SLR and work perfectly.

You are quite wrong in that statement Pete. The wider the lens, the more
pronounced pixel flooding becomes and the more "fringing" will occur in a
picture. Many people discard perfectly good lenses thinking this is
Chromatic Aberration when in fact it is just pixel overload flooding out
onto neighbouring pixels.

The whole notion of "Digital" lenses is the avoid this phenomena and attempt
to get the light path to fall at 90 degrees to the sensor thereby avoiding
the oddities caused by micro lenses on the pixels. Film (as you probably got
told by your great grand daddy) doesn't need such engineering. Also long
lenses almost never need such engineering as they probably do this anyway.

So? All "digital specific" means is that the lenses have a
small image circle so they can be made without the added
expense of covering 35mm size image circle.
What is more important than the number of digital specific
lenses, is the total number of lenses.

Number of _current model_, _genuine_ lenses that can be used
on digital bodies (without requiring adapters, and excluding
convertors, bellows etc)...
Canon (EF, EF-S) : 66 (source www.canon.com.au)
Nikon : 53 AF Lenses + 15 MF Lenses = 68 Total (source
www.nikon.com.au)
Sony : 19 (source www.sony.com.au)
Pentax : 18 (source www.pentax.com.au)
Olympus : 18 (source www.olympus.com.au)
Note that this is just listing the models available to the
australian market, since thats where I live (and I'm too
lazy to look at international websites). I would imagine
that all brands would have more models available in other
countries.

Now lets look at _current model_, major brand, third party
lense availability:
Canon : 41 Sigma, 18 Tamron, 6 Tokina = 65
Nikon : 46 Sigma, 18 Tamron, 6 Tokina = 70
Pentax : 35 Sigma, 12 Tamron, 2 Tokina = 49
Sony : 35 Sigma, 17 Tamron, 2 Tokina = 54
Olympus : 10 Sigma, 0 Tamron, 0 Tokina = 10
Once again, same disclaimer applies with regards to
Australian availability.

Giving a total lens availability of:
Canon : 131
Nikon : 138
Sony : 73
Pentax : 67
Olympus : 28


Additionally, Nikon and Pentax, and to a lesser extent Canon
and Sony, also have a wide range of old model 2nd hand
lenses to choose from, and there is also a fair number of
minor brand lenses.

Even with your higher figure of 34 fourthirds lenses,
olympus still only has half the number of available lenses
of pentax, and 1/4 the lenses of Canon and Nikon.

Now Doug don't you be letting any facts get in the way of a good whine!! ;-)
