DLC purchase?

A few years ago my uncle introduced me to Solasta and I loved playing it. I’ve had it the second on my wish list for at least a year but when the DLCs were released I didn’t have the money spare. However with all the news of the second being released soon I was tempted to do another run to refresh myself with the story. On top of that run is it worth buying the DLCs and playing them so close to the new one being released. I will probably get the new game either on release or pretty soon after but on the fence about getting the early access. Any advice would be appreciated.

TLDR: should I get the DLCs so close to the second release.
