This could end up being the better game, Brazil are desperate to win to save a little face so should attack and Holland have really nothing to win so have no particular reason to play dull backwards passing nonsense football. Against Argentina they didn't want to go behind because a final was up for grabs, poor decision and style and lost them the game but without that too scared to attack thing, they might just play like they did against Spain, all out attack.
Germany vs Argentina, a lot of people are talking about Argentina's solidity as a reason it will be difficult. But good teams don't completely buckle when put under pressure like some people seem to be expecting Germany to. Crap teams need space and time, great teams can be almost as good in tight spaces and Germany have multiple players who won't panic in such situations. Likewise Argentina faced a bunch of crap teams and/or teams like Holland who refused to put the ball anywhere near their strikers with zero quality trying to pick out those passes. Germany have better quality, the best attacker in the competition so far and a pretty decent defence.
If Argentina sit back I see Germany taking the lead, Argentina pushing forward to get another but conceding more easily as they leave themselves more open.
