Most ADCs these days are based on a sigma delta design, which is typically a bitstream running at approx 6Mbps these days. This is then decimated to the desired output resolution. The quality of the bitstream is the constraint, and is a constant no matter what the output resolution is.Even at 44.1k, the bitstream generates only about 20-21 bits of resolution. At higher sampling rates, there's even less resolution (because your are "spreading" the original bitstream thinner). If you don't believe me, check out the data sheets for most flagship ADCs - they tend to show higher noise for higher sampling rates.
Some people tend to refer to resolutions like 192kHz 24-bits as "marketing" numbers :-)
