Well I heard that they are continuing the anime and manga this May well there making the OVA to this but they have already began the series on a site called Anime Freak if you have heard of it go check it out I think that they only have the first 2 episodes out
The anime is really off with the manga version so I suggest you watch the series with a clear mind of any negima content (don't base everything from the manga if you been reading it so far). The new ova's that came out are in line with the manga however.
