Stop trying to put Il-2 into a coffin, it's still very alive!
And will be for years...
There's no recent information released about SoW. For all we know it might never be released (I think it will be released though). Il-2 certainly has months, maybe years, of being Number 1 WW2 Sim before SoW is released. After SoW is released, Il-2 will still be the best sim for all the stuff which isn't in SoW - Eastern Front, Africa, Pacific, everything late-war...
I think a lot of people will have both SoW and Il-2 installed on their computers for a very long time. SoW for Battle of Britain (and then other early-war European/Mediterranean theatres), and Il-2 for everything else.
