Don't be in too much of a rush to download this. Unpacking with Winrar, I get this diagnostic:
! C:\Wii\Wipeout.3.USA.WII-ProCiSiON\procision-wipeout3.r14: Packed data CRC failed in procision-wipeout3.iso. The volume is corrupt
! C:\Wii\Wipeout.3.USA.WII-ProCiSiON\procision-wipeout3.r93: CRC failed in procision-wipeout3.iso. The file is corrupt
The sfv file all checked OK! This is very similar to what happened with the first release of Toy Story 3 a couple years ago.
We can expect a nuke, and a repack or proper coming out later.
EDIT:
Just tested if it's still usable, and it actually is. I tested the iso with Wiimms ISO Tool, and it reports everything is fine:

+OK .1 DATA SSVE52 /cygdrive/c/wii_iso/procision-wipeout3.iso
I also converted to wbfs and rechecked the scrubbed file:

Old version of Wiimms ISO Tool, but I'm sure it can be trusted. So, you don't have to wait for the repack or proper, after all. Just make sure to tick "Keep broken files" in Winrar before you extract.
