I don't know about weapon systems,. for example standard lasers are viable weapons right now (though we will have to see what the aformentioned 3rd generation tech brings). standard autocannons should only go away if Ultras can fire special munitions on single fire (and Ultras need to unjam in the field)
standard one shot SRMS absolutly should go the way of the dinosaur, and the A and B pod need to be merged into the AP Pod
