That's one more nail in the coffin. An end for the CFE would probably mean the end for non-standard treaty-dodging weapons such as 98 mm mortars. More importantly, it would remove a Rubicon between now and arms racing time.
The latter is of heightened interest because the Russians announced (again) a major re-building of their conventional ground forces during the 2010's.
The blog of choice for keeping an eye on their efforts is in my opinion Russian Military Reform.
