The TV broadcast will start at the beginning and should continue on for all 26 episodes by September or October.
The TV version should catchup with the OVAs in September for the last four episodes if the release dates are similar to how they have been up to now.
Also I'm fairly certain up to episode 10 can be found in places. Episode 11-14 of course just came out, but they will likely show up someplace in the next month or so if I know uploaders habits well enough.
The Anime starts airing on April 7th at 5pm in Japan.
