Inversely, will a high end DSLR make me long for a P&S's small size?

For motion itself, will a new canon point and shoot (digic5) have the same movement quality as the 5d mark 3 (their nice digic 5 slr)? I understand that the lens quality will differ (chromatic aberration, etc), but what about seeing how the video handles movement, skew, and motion? Hos much of it is the card itself and how much is the post-card processing? Will a $200 camera's video sample give me a good sense of the $3500 camera's video capabilities?
