I'm sure you are aware of what 'beta' means.
Also if you read on their site it states 'battle of britain 1940', and if you check plane trees they have spits 1s and emils.


A little bit of investigation never hurts before being negative.

IIRC they paid for the IL2 engine under license. Kept the models and FM/DM with minor updates but created a new engine.
If I'd paid for the right to use it I'd not be keen to "give" back info to a competitor

All the posts I've read during the Wings of Prey Gaijin development said that they did build their own game engine, but borrowed the IL-2 FM from Oleg. Oleg even posted he was pissed that after he had given the FM to Gaijin he asked them for some information on Dover for his own SOW project and they ignored him. ROF is the only developer I'm aware of that was using the original IL-2 game engine, but soon found it didn't work for their needs, and decided to develop their own game engine.

I see nothing to change my mind. The promo video shows Stukas tangling with
grey-camo tail-banded cannon armed spits, over Kent. The website shows a Spit II
in the 1940 list-sort, with the same appearance. If they want to show a trailer
of their product to impress people, why make it full of errors? *sigh*

So it does not matter that it is a beta ?



Spit 1 is correct, also players will be able to choose their own skins, so it's no big a deal imo as everyone will fly in a skin they want anyways.



Also you know that the Spit 2c was armed with 2x20mm, right?

I took a quick look at the BOB map section of the WarThunder site and it still only mentions Dover, which would lead me to believe the BOB map still won't include any airfields for the Axis forces. If I remember correctly some of the other maps will haave airfields for both sides of the conflict. I also didn't see any CEM mentioned. Flying with even a weakly implemented CEM is far more immersive than without one. That said I will still give WarThunder a go, but I'm beginning to doubt that it will stay on my harddrive any longer than WOP did.
