What's even more important - and everyone seems to forget about this:
Operation Arrowhead has been announced - read it from my (virtual) lips: a-n-n-o-u-n-c-e-d
and 75% of the community are on a rage as they would have said it will be released next week.
The only thing we know right now is that its a standalone expansion in which the ArmA2 addons can be used as well.
We also know that its set in the fictional country of Takistan and that the US Army plays a role.
We seen two screenshots, one with an Apache and one with a woman in her burqa.
No release date, nothing. And wherever I look people are going nuts screaming and bitching about BIS not patching ArmA2 anymore, milking their customers and gawd knows what else... Geez the expansion has been announced - nothing else. Marketing tactics shortly before an important exhibition (gamescom).
Really some people are horribly overreacting here. And yes the announcement caught me by surprise too and at first I was like WTF.
Calm yourself down there :).
The main reason for this is that THE DEVS have said that any fixes to the Engine that are applied to the new expansion will be available for Arma2 owners for free after the release of the expansion and like you said this maybe 6 - 12 months away and nobody want to wai that long..
That maybe all well and good but people want BIS to fix the engine problems in the Arma2 exe now not wait for some other game to be developed first and then any fixes handed down .
Lets look at the other side , BIS will now release beta patches for ARMA2 , does this mean feedback from the patches will be applied to the Arma2 game and exe or wil lthey first be used to fix the expansion exe ?
now i dont see anything wrong with people wanting BIS to fix the Arma2 exe and not try to make another game first, seems logical that people would want that.?
whether you like it or not BIS PR have certainly created this situation and only BIS can be blamed , not there customers.
