You won't see any company mergers pre-teased in a forum so I don't think that's it.

Someone mentioned over at the DAZ forum that the wording was similar to the announcement made when they bought Bryce. So I think it's possible they bought another program. Or even more likely they will be having a DAZ special sale for a limited time for some big program they haven't sold before as they did a few years ago with Modo. This is a slow time of year for sales of anything, so a quick partnering with some company looking to expand their user base and generate some quick cash is probable. It was around this time last year that messiah made a lot of noise and generated some quick cash, so maybe another company wants to do it this time but with DAZ handling the transaction and quickly getting word out to its users.
