Nice to see they've done right by the original design. I imagine the stock pups in the Squiers are regular humbuckers made to look like WRs, as was the case with Fenders too until their reissued the pu.
Yes, the Fenders of the 70s that came with them had 1meg pots.
It's interesting that Seth Lover's two seminal humbucking designs, the PAF and the WR, were both trying to keep as much of a single coil vibe as possible.
