Could be wrong here, but I think Gamma 1.8 was based on the fact that OSX pre-Snow Leopard (10.6) used default Gamma of 1.8 and, more importantly, Quicktimes used to be encoded with Gamma 1.8... As Paul suggests, this is easily over-ridden in defaults.
Gamma 2.2 is the default monitor gamma however, for the past few years, most Quicktimes are encoded sRGB -- I encourage you to view the movies in Quicktime and compare them to the same MOV loaded into a read node in Nuke with Gamma 2.2 and the same clip loaded in at sRGB -- pay special attention to the blacks. Now, this *is* assuming your not viewing in QuickTime Pro with "Enable Final Cut Studio color compatibility" checked. In most cases, you may find that sRGB is actually a better match than Gamma 2.2 -- let me know if you guys are seeing different results! And then there's the case where your footage was ingested/encoded by an ad-hoc setup by someone that may have no interest in correct settings and just wants to get it out of the way ASAP... but, I'm sure that's never happened to any of you ;) Bearing in mind that Nuke's defaults are meant to start us off in the right place for a majority if cases, I agree that the Foundry might consider changing the default from 1.8, however, I'm not sure that Gamma 2.2 is the best choice considering the colorspace setting is meant to account for what the footage was encoded with rather than the viewing device -- sRGB may be a better choice. Regardless, no matter -- that's why we have the ability to over-ride the defaults to fit our color pipeline. In cases where the Quicktimes are actually Arri Alexa captures or R3D proxy files, you may not want Gamma 2.2 or sRGB... By the way, since we're suggesting changes in the Read node's behavior when loading Quicktimes, we may also want to change the default to "start_at" 0 in order to keep the MOV 1:1 with most Apple apps. (Yes, we over-ride this in our custom settings too) Just my $.02...
