No they can't be.I don't really care about this discussion but all those points can be an opinion depending on how you look at it.
1 - "Costs more" is NOT an opinion.
$1000 is more than $500 USD. That is not up to opinion.
2 - "Outdated in a week" is NOT an option. Same issue as with the numbers, only dealing with measurements of time.
One week is shorter than one year. That is not up to opinion.
The time span from Jan 1st 2011 to Jan 1st 2012 is one year. That is not up to opinion.
3 - "No games" is NOT an opinion.
Even simpler as we're talking about pure numbers again...
Something like "$500 is more than $1000" (to use one of my made-up examples) is not an opinion, and you shouldn't let people go on thinking they can just make up bullshit and slap "opinion" on the end to avoid liability.
