Hey folks...just recently found out about this new sim... very much looking forward to it!
About the original topic...
Well, as the technology gets better and better I suppose we will see some kind of leveling the playground... I.e. vast differences and between planes advantages/disadvantages of particular types will be ironed by the quality of materials used, advanced physics (both for machine and the pilot), low/good fuel quality. (un)reliable engines, ease of damage repair etc. etc.
About the low alt furballs turnfights and online duels... I suppose we all have our joys but I know I would enjoy good quality campaign more than anything else really.
