This will be quick ... there are four matches tomorrow, the first of which begins at 3 in the morning my time, so just watching them will be nearly impossible, let alone come up with something to say about them in advance. I've mentioned that I entered one prediction contest, so I'll look at that and assume I'm correct for once.
France-Australia (Group C) 3:00 AM (all times Pacific). France wins, 3-0, goals by Olivier Giroud, Paul Pogba, and Antoine Griezmann.
Argentina-Iceland (Group D) 6:00. Argentina wins, 2-0, goals by Lionel Messi and Gonzalo Higuain.
Peru-Denmark (Group C) 9:00. Denmark wins, 2-1. Both of their goals by Christian Eriksen, with Paolo Guerrero scoring for Peru.
Croatia-Nigeria (Group D) 12:00. Croatia wins, 2-0, with goals by Mario Mandžukić and Ivan Rakitić.
