I think with c4d there are a lot of ‘amateur/enthusiast and student’ users. This may have something to do with the availability of lesser versions and price. I was a pro when I purchased XL5 and price never came into it. £405 for a .5 upgrade is getting to be more than most might expect, but I think one forgets what you get for the money what with all those extra modules. You could argue that these features should be part of the core app- if you purchased them seperately they’d add upto at least £1500. I never included dynamics, SH or the toon thingy.
If you look at XSI and Maya, both apps have been largely developed ages ago, whereas c4d being a new app relatively speaking is in need of cash influx to pay for development which has only just occurred in the past year. Maxon has probably never had the cash influx that both Maya and Softimage must have had in their ulta expensive era.
For a freelance or pro c4d certainly isn’t expensive, but its obvious that Maxon are riding the crest of a wave now that the app is perceived more as a professional tool, (with BP in mind) rather than a mid range app.
c4d still doesn’t have nurbs modelling and so there’s still the added expense of using a third party app like Rhino. I think this does make c4d a bit on the pricy side compared to other apps in the current climate of ‘desperation’
