What are the chances we'll get a long term roadmap of promised features?

I understand that developing these features is a moving target, but I wish we could just get an update on what features are still being considered. Things like Assassinations that were mentioned early on, we just haven’t heard about for like a year.

its a good thing if there share a long roadmap with us what there are planning to add in the game for a full year more.
and then it can be look more like this exemple more what there can do.

for the campaign and multiplayer: we are planning to release this year the assassinations.
for the multiplayer we are planing to release 10 new game mode’s.
for the campaign we are planning to add more story line missions and also some new things to make sure the players can keep enjoy the campaign more with this new things.
for the multiplayer we are planning to release 20 new maps.
for the campaign and multiplayer we are planing to bring some old weapons back from other halo game’s.
and we are planing to bring fireifght back in a new version for the one’s that own the campaign.
and we are planning to fix this type off problems this year.

this is more a good exemple how a year roadmap can look like.
so long there are no date’s of with thing is going to release will there also no hate about it if its going wrong.
and the communety knows what there get in a full year on new content.

the only thing that can get wrong is if the things on the year roadmap not have come out that there will be hate then like we have see this year all a lot.
