Short answer is 'difficult to tell' - the maths above is dubious to say the least (fatbus think about it...).
Nobody actually knows what's going on.
Yes - the rules changed this year to increase the 'hard time' requirements; however, that FCI expires at the end of this year and will most likely quietly slip into the ether like most decisions made by that particular company executive.
So - you are left with waiting to see what happens on the commercial front which is anyone's guess...
As far as I can tell, EK is still not a bad option for a relatively short time wide body command - look at Cathay: probably 12-14 years for joiners right now, Air NZ probably 15-20 years, Qantas similar....
Like anywhere, 'you pays your money and you takes your chances'! The job here depends a lot on your attitude, if you come with a demanding attitude and get outraged by every inevitable change in conditions - stay at home. If you can view it a bit more as an adventure and enjoy the job for the good parts, then come and have a look.
I've been heavily disadvantaged by the change in upgrade policy, but after the initial disbelief - realise that it will probably change in due course for a number of reasons and the overriding factor will - as always - be commercial requirements. There is no airline in the world who can guarantee upgrade times...
Good luck.
