The Amiga's hardware was designed with television output in mind -- not just the clock speed but the genlock. A "Toaster for PC" would've required additional hardware. Such systems did exist -- Matrox Studio being one -- but it was somewhat more expensive (and way less sexy) than the Toaster.
NewTek did make a Video Toaster for Macintosh. It came in a box that connected to the Mac's SCSI port and was largely controlled via a Switcher interface on the Mac. You may have figured out that the box was a complete Amiga 2000 system with the Video Toaster add-in cards installed.
As the Amiga declined, NewTek saw the writing on the wall and released a Video Toaster for Windows NT PCs. Today, a turnkey version of this system is available under the name TriCaster.

But again, the sexiness just isn't there now.
