The A-10a has already got a new model. And its not just the C model copied over, its accurate. The Mig 29 inspite of requiring an upgrade to current EDM standards, is still relatively in a decent state and probably will get an upgrade in the future. The Su33 on the other hand is the last on the list of flyables to get a model upgrade. All the original LOMAC aircraft will then have current-next gen model upgrades.
