Not to downplay your excellent, informative post, but I think I can sum it up fairly concisely. Marketing is the entire business strategy concerned with entering, gaining, and maintaining the share of a particular market. Advertising is one subsection of marketing tailored to individual products in order to increase awareness of a certain product so that it meets, at the very least, mininum sales projections.
As for Sony's plan with Move, I think it is an interesting study in contrasts between the Kinect and Wii. Sony with Move is appealing to their core first because it seems they have decided that it is the core who would be the hardest to convert over to buy a Move. Implicitly, Sony employing this marketing strategy has enough confidence in the Move itself and their development studios that they can cater to the non-core at their whim and still meet their sales projections.
I am unsure whether this strategy will work, but regardless of how it turns out it will be a fascinating learning experience to observe.
