North was not doing so hot - they've been looking for an acquirer for a while now and were facing running out of money. So, not exactly a promising startup at the current moment unfortunately. Based on the announcement that second gen focals are cancelled as a part of this acquisition, it doesn't even seem like they're pretending it's to continue the product line etc - it seems pretty clearly for the tech/patents/etc
