i don't think that will be happening any time soon for me. my base set is done but there are still areas where i can expand into. for example at the moment im building & testing a winter setup for 0 to -10°c. and at the same time im planning a setup for car camping as i'm getting a new van soon.
also most of my good stuff is solo gear but im starting to improve duo/3p set ups now. also i consider clothes to be a part of my "gear".
but some parts are already satisfactory and unlikely to change. like water treatment, fire starting, basic tools, navigation, hygiene.
