Does anyone know what happens after we reach level 130? Is that it? Does 343 intend on expanding the number of levels we can rank up?
Play for fun. If you still need to play to make numbers larger, you can play for CSR on individual playlists.
At this time, I don’t think 343i plans to increase the ranks. It may happen, but for now, I wouldn’t hold your breath. If you’re still looking for a challenge, try completing all the commendations, or go for 50 CSR in your favorite playlists.

No!
There are other things, like Stances to unlock, tons of weapons and other things to master in terms of commendations, improving ones sill, improving KD (if it is important to you), and so very much more. SR130 is only a tiny part of it all.
CSR? 100% Commendations? Having Fun?
Work on commendations. You should have been doing that from day 1 instead of going after the 130 which was going to come eventually anyways. If you care about numbers though I recommend just focusing on your CSR score.
130 is a number, skill is not…
-The SR ranks are how much you play the game, commendations can last months after being a 130…
-CSR is probably the most important challenge, some will never see 50
