The future off old school Marines?

With the release of 9th and the new Indominus boxset, we have the next wave of primaris releases, filling in some of the more obvious gaps in the inventory. 

Up until now, primaris units only had plasma and flamers with everything else being dealt with by the old school marines. While we still don't have an answer for foot mounted lascannons, we do now have melta equiped primaris. 

Not the best picture but we all get the idea. Long range melta, no doubt with different models, much like Intercessors and Hellblasters. 

We also got lots of combat upgrades, with Blade Guard and Assault Intercessors. The blade guard bring storm shield to the masses and Assault Intercessors bring chainswords. 

I will say that the Blade Guard do look good and Assault Intercessors (below) definitely carry the assault marine vibe (but where are the jump packs?)

The other new units are the bikes and, not pictured, the Invader ATV, which fill the roles of bikes, assault bikes and land speeders between the two of them.

 While the land speeders role is not entirely taken by the ATV, a lot of it is covered and I believe that there have been leaked pictures previously showing a land speeders type primaris vehicle, although the picture was terrible and it's pretty hard to make out anything. 

So where does this leave our old friends, well honestly in a pretty bad spot. From my memory, which is pretty bad, there are really only 3 units or models that don't have some sort of replacement. I've touched on one, the lascannons devastator. As yet there are no primaris Marines equipped with lascannons or similar
