Making every copy operation excruciating just to support the few cases where you might actually benefit from the fullscreen 3D copy visualisation with Dolby Surround Sound isn't a design tradeoff with which I've been particularly satisfied. It'd be fine if you could hold down Shift or something to say "please don't muck about". It's even worse when it's putting stuff in the Recycle Bin, at which point you really, _really_ don't care.
Your mileage is entirely welcome to vary, and perhaps the performance of this new dialog is such that I won't notice it as much as its Vista and Windows 7 counterparts. To be honest I couldn't work out the Windows 8 preview to the point where I could even find a file, let alone copy it somewhere.
I'm not clear what your complaint actually is. Are you upset because the dialog exists at all? Would you rather that you get no convenient way to know when the copy is complete? Or are you annoyed by the extra visualizations and such? It seems like you could simply not expand the additional info.
As for the recycle dialog, I'm pretty sure that's gone in Windows 8.
