Here's a nice article from
SoS (I love that magazine). It details a project that was done, using Pro Tools for various aspects.
IMO, Pro Tools is overkill for this type of project. A well spec'd native system running any of the major DAWs should be able to handle the project from start to finish without a glitch.
However, there was a time when this was not the case & 30-40 mics, maybe a half dozen headphone mixes, required the additional power of a Pro Tools system. But just like the home studio has grown from the 4-track tascam, there are some studio's out there recording a hundred sources, or playing back 500 tracks, while providing effects processing, routing processes, real-time pitch and tempo processes, etc..... without a glitch.
That market is shrinking & Avid (Digidesign) is having to adapt. They've yet to focus on the home market or today's small studio, where chopped down versions of their flagship is hardly competitve. At the same time, native based systems with their extra features & 64 bit support aren't competitive on the high-end.
