N+ developer Metanet Software have updated their blog with some good news - The 3 downloadable level packs are now in submission over at Microsoft!

We just submitted three downloadable levelpacks for N+ XBLA (one of which is free), we’ll be posting with more details as soon as we get a launch time. In total there will be over 750 new levels! The multiplayer maps in particular (over 300 of them) are a lot better than the ones that came with N+, since we’ve had more time to learn what works. We made sure to include more co-op maps, since they’re apparently quite popular.. these ones are even harder, so start practicing!

There’s also a small bonus in each pack which will remain secret for now.. or will it?!

I assume they won't come all out straight away, probably separated by a few weeks each. Might be time to get back into N+ again. I got up to the 42nd group of levels I think, quitting out of frustration. Might try and get those multiplayer achievements too...
