Whether AvA will come back alive, I mean in the essense of when it was first introduced, will depend on HTC adding new aircraft to fill the gaps and making more of balanced and historical planesets.
Panzzer, I wrote back to you in the "general discussion" about this, and the way I see it is that the new Ma setup will give people the diverse and balanced fights.
Thats already a major settlement made for the early war planes, but to make it historical, you will need three times as more planes as we have today. Whether or not you see this happening, the AvA is dependent, as is the MA (including the new setup after all) of new things happening. You need something new to bring back the growd and keep them interested.
Repeating the same old BOB map with Spits, Hurri I's, 109E's and 110 C4's or what ever, will only decay the AvA AND ALL Battle of Britain events as a whole. Until You offer something new, like HE 111's and some scheme to use them in (like bombing of London), you will have hard time convincing people it's actually something new and interesting to try out.
What's new now is the MA setup, so people will be interested in that rather that the old BoB setup.
The BOB map is only an example. Same goes to any and all AvA historical maps (theres not so many any way).
In conclusion:
What EWA currently supplies is balanced fighting with diverse enough (even though not historical) early war plane set.
What AvA currently supplies is the same old BOB map with the same old same old, and TRULY same old plane setup we (I) enjoyed for a month ages ago and then got fed up with.
