Nazi German Arms Development after an Axis Victory

So, i've been thinking about what specific weapons of war would receive further funding for upgrades after a hypothetical axis victory scenario in WW2's european front (disregard the plausibility). Take the current time frame as the middle 1950's to early 1960's. What would happen to the Stg44, the MP40, the Panzerfaust and the german tank models when they would become obsolete and what upgrades or new weapons would replace them? What new weapons developments and inventions would we see here, aside from nukes? How would such new developments be affected by the nazi war doctrine?
 
For one thing, the E-100 series would come into fruition along with more and more mechanized units becoming commonplace in the German armed forces than there were in 1939. The STG44 would be replaced by a more efficient successor, say the STG45 or 46, along with the old bolt rifles being phased out by the end of the 40's. The MP-40 would still see service but that too will get replaced by something like the MP-50 (though I can imagine it will be seeing service with special forces units and paratroopers and vehicle drivers than regular units).

Oh and one thing's for sure, don't expect a lot of Luftwaffe 46 stuff to appear; while granted I'm more lenient toward them than most folks on this board but it's established that at the very least, they have a lot of flaws to be ironed out or at worst not very practical at the time.
 
TBH, the how and when the victory comes about, and the type of victory, are key to considering further development. An "everyone between the Atlantic and the Urals (including certain islands) is crushed underfoot" victory is going to demand quite a different force structure to a Brest-Litovsk Mk 2 in the east (likely not possible without Hitler dropping off the mortal coil rather early) and semi-inverse-Versailles in the west. I mean one calls for a mostly COIN and constabulary focused army while the other has to worry about a rump USSR rebuilding; the United Kingdom, humiliated but unbroken; post-Vichy France possibly trying to avenge it's humiliation... with an implication that more of an armour and mechanized infantry force is needed.
