I think that this is the best approach. There is a huge difference between the 4mpixel of a pro camera a decade ago and the 12mpixel of the FF 5d.
I just have not seen an appreciable difference with the latest 18-21 mpixel sensors that are nearly as dramatic, if at all..
At your large prints there may be more visible detail when viewed close in... I rarely go beyond a 24x36 print.
The whole point is that the 5D2 offers features, beyond the megapixel count, that don't exist on the original 5D, which make shooting in the field a mush easier task, especially in low light and darkness. For example, I just spent six days shooting in Monument Valley, usually setting up in the dark for sunrise shots. Having Live View on the 5D2 allowed me to focus in the dark on an edge of one of the the buttes...zoom in to 10x and dial in the focus. Can't do that with the original 5D...the AF won't be accurate, if at all functional, under those conditions. The LV also makes using strong ND filters easier...LV will 'see' thru a filter stack, allowing you to compose, focus, and meter with the filters in place. I've managed, with LV, to see thru filters adding up to 12 stops of light reduction...can't do that with the original 5D either. If you're a serious landscape shooter, the 5D2 is a godsend, whether or not you take advantage of the added megapixels.
