Only the Artillery existed in the timeline while FASA ran the show and PGI has mentioned before that they left out the Artillery because it was just to hard for them to adjust the weapons to the kind of game they wanted (hence why they later gave us arty strikes and air strikes as consumables to 'replace' the missing weapon systems).
Rifles, Grenade Launchers, Rocket Launchers, Mech Mortars, etc were added by later companies and usually they added these to the later timeline... However some retroactive builds were added using those weapons... Traditionally the next ballistics we would see are near 3060 (8 years form where we are in MWO) with first Light and Heavy MGs and then shortly MG Arrays along with Light ACs and Light/Medium/Heavy Rifles (all 3068)... Though Light Gauss was retroed to 3056, so beats all of those...
Btw from Sarna "[color=#000000]The first modern version of the Rocket Launcher was developed by the [/color]Marian Hegemony[color=#000000] in [/color]3064", so those aren't available yet.
The inability to balance the existing weapons is a good reason not to add yet more. So even if you did want to accelerate the timeline, it's probably not a good idea.
