1. Calm down !
2. I really hope english isn't your native language, otherwise it looks like you left school in the age of 10.
Please read the sentence again:
"this port is being done internally by their own developers, which isn't a huge surprise given their past public statements and already existing internal linux client work"
-> It's not a big surprise that the port is done internally. This has nothing to do with the game being a surprise or not
-> It's not a big surprise that the port is done internally, cause they already did internal linux client work. This shows that blizz has internal Linux knowledge, therefore doing the port inhouse instead of hiring externals to do it.
I hope everything is clear for you right now.
If they really wanted to bring a Wow linux client, they could have done that years ago. They could also do it NOW, cause it seems to be working already. But this will not happen.
Imo it will either be D3 or SC2, but my bets are on SC2
