Don't pretend that you have inside knowledge or that you know exactly how investors and shareholders react. It is far more likely that they will applaud any initiative that A) brings more value to the portfolie, ie raising Blizzard share price and B) increases Blizzard profits, ie raising the amount of dividends they get. Everything else is just conjecture and random noise.
If you'd read my second post you won't say that. I did say, that it's possible that shareholders urge Blizzard to introduce Vanilla again after what happened with Nostalrius. And I never pretended to have Blizzard "insight knowledge". But I know how economy works and I know how marketing works - what of course is part of economy.
Your B) isn't correct. A raising share price doesn't mean raising dividends. Raising profits doesn't mean it too.
That "we lost the source code" was a lie is obvious. Who the fuck lose source codes in times of big data? Probably even google have the original source codes of Vanilla. It's not possible to lose things like this in times of internet and big data. Who ever believed that is simply stupid.
if the final answer was a NO you would already have it.
I personally say after the thing with Nostalrius it's a 50/50 chance that Vanilla will be introduced again. But I wanna remind you that Blizzard said about 10 times NO to Vanilla in the last 5 years.
We can only speculate.
