Looks like F1 TV is gonna go live for the Spanish GP. For the US, it's $2.99/Month or $26.99/Year (or 24.29 with current promo). It seems reasonable.

If you go to the content schedule, it looks like the US gets access to all the available features but there will be a 2 day delay for replays. I don't think I will subscribe because I would only get this for the ability to watch replays, and ESPN already offers this (commercial-free) with a lot less delay (only a couple hours after the live event). The other features are neat, but I'm just a casual follower and don't really need the additional analysis.
