Rumudiez, I ended up discussing this with sawedust but edited it out to not talk strategy in the tournament thread. Let's just say that the death ball is not the reason why Protoss is nigh-unbeatable right now.
Also the Homestory Cup thing was really a numbers game. Ro32 started 12 P, 10 T, 10 Z and the numbers for Ro16 were 6 P, 5 T, 5 Z...so it basically was just a flat reduction in half. Protoss took the 1st, 3rd and 6th place spots. The highest placing Zergs faced against Protoss and got 3-0'd, 3-1'd and 3-1'd respectively in their final matchups. MC 4-0'd Sound (Terran) in the final.
There are some really important matches from this season of GSL Code S and GSTL that you should watch that show how easily a low-ranked Code S Protoss can handle the top Terran and Zerg pros early to mid game. Not that that guarantees a win but there seems to be an advantage.
Edit: Not to let this discourage anyone. Honestly I doubt any of this has an effect on those playing. The masters Terran players we have could roflstomp me without trying hard. :B
