You can't play the favorites if you want to stand out, so some are against the current thinking. And sorry for #10 which is a downer prediction...
1. Hamilton will complain about Bottas.
2. Bottas will force an error on Hamilton which will see Hamilton retire from a race.
3. Neither McLaren will see the finish line in Australia if they even manage to qualify.
4. McLaren will only use Honda power during the course of the 2017 season.
5. Honda will not leave F1 during or immediately after the 2017 season.
6. Honda will show enough promise to pickup an extra team for 2018.
7. McLaren will score at least one point.
8. Alonso will leave McLaren at the end of 2017.
9. Kimi will win at least one race.
10. A race will be red flagged due to a significant crash.
Bonus (doesn't count)!
11. Mercedes will remain with Mercedes power throughout the entire 2017 season!
