The future for a current Squeezebox user

I've been contemplating this question for the past year and a half or so since Logitech has essentially discontinued its Squeezebox line (at least, the Squeezeboxes as I once knew them).

I've been using Squeezeboxes since the pre-Logitech Slim Devices era, about the past decade or so. I have a sophisticated home system using them. I have the Logitech Media Server running on a Linux box running an enterprise-grade Linux distribution, and this houses nearly a terabyte of FLAC files. I have a Transporter connected to my big rig. Four rooms are connected to a Squeezebox Classic, and the guest bedroom and garage have a Squeezebox Radio. All are connected via wired ethernet. And I control them through either a web browser (served by the LMS on the Linux machine) or the Squeezepad iPad application. It's a slick system and works great.

The question is, where do I go from here? I don't feel the need to move on to anything else in the immediate future, but I'm concerned that this may eventually leave me stuck with a dead product line. What other options are presently being developed that might provide a migration strategy? I want to continue using the Linux machine as the music repository, and continue using FLAC as my primary music file format.

Thanks in advance,

Michael
