I believe the GP was referring to the train arrival and other dynamic signage, rather than the static signage that exists now.
Bang for the buck, it feels like getting wifi (and cellular data) into all stations is way more useful and future-proof than a bunch of displays that are going to look quaint and outdated a year after we spend billions getting them installed.
If you want to know which track is downtown, or what the stops are on the express, the existing maps and signage will get you there. If you want to know about service interruptions and arrival information (or potentially connecting train information or more detailed trip estimates based on subway traffic in the future), then unless you can understand the static coming out of the loudspeakers, you're out of luck.
It's taken them more than 10 years to get arrival signs into the stations, and (as above) they already seem very outdated, with insufficient information many times (because three display lines is not enough lines for busy stations when you're waiting for a 6). Plus most stations still don't have them, which seems absurd given that every other subway system in the world has them.
