Apparently the Spanish station ("La Mega 97.7") had some issues getting their studio set up so the launch date has been pushed back. Kiesewetter says they're targeting 11/15 and La Mega's Facebook said they'll definitely be on by 11/19, so I guess we can expect the launch sometime that week.
For a likely preview of what the station will sound like, check out TSJ's station in Columbus:

The music is primarily Regional Mexican, but they incorporate a healthy dose of Latin pop, Tropical, and even some Salsa and Recuerdo-type classic hits--an unusual Spanish mix format, from what I've seen. And of course plenty of jocks cutting it up
en español. From what I'm gathering, my guess is that La Mega Cincy is going to be very similar.
(A disclaimer on the Columbus link: They do stream online, but they don't seem to be the best at restarting the stream quickly when it dies.)
