First, the R46 V Train photo is nothing new, the V line has always used R46 coaches (or R44s) since it's 12/01 debut.
As for the R68 A train, I hope it's true, they should run those cars more on the C and E lines, they are both completely underground as I said in another thread, and ought to be swapped with the R32 & R38 to run on the open-air A line and the Rockaway Park Shuttle.
