Too bad that this is the first criticism. I am going to defend the entire Prime team here, because I am really disappointed that sometimes there is only complaining, even though a step forward has been announced. The WI-FI module was already installed before anyone could even ask for features. The plans for a next-gen console generation were mapped out before we as a community could turn these plans upside down. The team listens, they are aware of all wishes and a number of them are high on the list. Some are coming, some are not. But some things that do come are simply not arranged in a day. I have never seen a post from anyone with the question and the solution in 1: "I want feature xxx and here is the completely programmed code for feature xxx, extensively tested and error-free, you just have to zip it and release "
Plans can be (partially) changed, but this announcement confirms in fact that these units were ready for the future and are on a bigger roadmap. And whether or not this is a feature that you have been waiting for, it is a big, logical and very good development for the DJ industry. The generation that is coming now has never bought a record, cassette, CD, DAT, MiniDisk, DVD or paid download. A new generation of DJs is emerging (now) that is used to everything on demand, with a simple subscription. A generation that expects the same options and access on every device on every platform. And I applaud for Denon that they are already responding to this and am glad that they do not keep thinking in just the current ways. Change has happened so many times before, from vinyl to CD to mass storage. And now we are going (step by step) to the cloud.
It opens doors for a few more steps later, where you have access to your own music in your own Google Drive / Dropbox / OneDrive, for example, and you are happy to log in if your USBs are unexpectedly forgotten, stolen, defective or infected. Your database runs in the cloud, so your own local or online and streamed songs also all have all saved hot cues, loops and beat grids (and yes, also flexibly before that time). Changes on database are realtime… And that on every device, 100% in sync and backed up. More doors will open in the future with an online device and for the development of the device / software itself, that too can be improved more frequent with the recently assigned development team and online access.
The development is going step by step, the ideal will never be achieved for everyone, but with teams such as these now working hard for Prime, they are getting a bit closer. One time with a feature for you, the next time with a feature for another.
Unfortunately, development takes more time than coming up with ideas. I too often have difficulty with that (with all kinds of software), but we will have to learn to live with that. In the meantime enjoy the technology that has been brought to us. And preferably with good music, because in the end it’s not all about features, but music… And making people happy with those tunes (little matter how they come in or out of your unit or on your screen 
)
