some of the optimistic ones amongst us are still speculating oleg might add in some form of integration with other sims, possibly tanks or other mobile armour, maybe ships, but a fps element is prrobably the least likely next step.
oleg definitely previously speculated along the lines of integrating these other aspects of war sims with his flight simulator project, but some other companies have aimed for this before and found the bone to large to chew. it is possible that some of the delays with olegs project are related to this aspect, and one of olegs colleagues posted a couple of years ago in another flightsim forum about "driving a tank to london" in a fictitious successful german invasion scenario. at the time this was referred to as something they were working on, and had already integrated, but there was no further mention of it later on.
right now the pessimists are even doubting the BoB project is still in progress, i tend to be on the optimist side, albeit with the help of some regular supply of armagnac to keep the spirits up, and still hope that when in the next months we finally get further news regarding BoB it will surpass our dreams. the game engine and grafix have been totally revamped from the original BoB idea (just compare the 2e 1946 dvd artwork with some of the screenshots from work in progress from the last year or so), and i think oleg has still persevered with some sort of 2e sim integration project (naval ? strategic control of war resources and ground troops, tanks etc..), but that this expansion aspect will be built into the servers only and will be added on as an expansion at a later date (either by 3e parties or oleg himself). did i say i was an optimist ?
time will tell
