I'm not too bothered to be honest.
I'll be flying in Russian so if I'm able to perform the most basic functions in the Russian cockpit then it will give me an edge when the english version is released.
Anyway, it's win-win. We get the Kamov and ED gets our money. Twice!
1) - There will be free flight mode available. You will also be able to make your own free flight mission if you choose.
2) - No. But there will be people converting the russian class tables into english ones. I know a ruskie that can translate it for me so I can upload it as a 'patch' if ED allow it.
3) - DCS: BS will include a 'casual' mode which will allow you to quickly begin flying without touching any of the switches/knobs.
