No, I think your wrong Crash. We will at first undoubtedly get just the one map but more than one 'plane! They won't be generic maps either but as accurate as they can make them. The RoF model is to pay for continuing development it's true but 777 Studios understand that to do this you need a very high quality bar in everything they do. This means not only exquisite aircraft and maps but that it must all work too. Without this their revenue stream is threatened - people simply won't buy.
I think we'll just have to get used to this business model. The market for a high quality combat flight sim is just too small to support a large studio knocking out one highly complex, complete game in one go. If sales were in the Call of Duty range, i.e. millions of units sold within two months of release then it would be different but unfortunately for us the genre just does not work like this and cannot support these kind of sales figures.
Three or four years ago Jim got Miss Kleaneasy, the UBI forum manager, to find out about sales of IL2. She came back with the figure of just under a million copies of all iterations of IL2 sold by UBISoft over an eight year period. Thats pretty small fry these days. How many copies of SkyRim have been sold since it's release earlier in the year?
What we know of CoD development from Luthier was that the 'planes were uneconomic to produce, taking upto six months work for each one, they were stuck with a game code that was lumpen, easily broken and just plain awkward to work with because of decisions made under Oleg several years ago.
I think the entry of 777 Studios and their team into this is very good news indeed.
