Since i pretty much got everything i need, if i keep the lootboxes i earn now and open them when new content is released, will i be able to get the new stuff from those boxes

No. Loot boxes items are "rolled" at the moment you earn the box. Whether you open it today or 3 years from now, those boxes contain the same items. So if we add new stuff to the ecosystem, you will only see it out of brand new boxes earned after the release of that new item.
