The 5TH Cell guys must be psyched about this one. Though the review embargo for online publications doesn't end until Monday, the embargo on print reviews must be different (due to that production cycle?), as we currently have TWO reviews from two magazines.
Now it's hard to say these two guys are...well...unbias. After all, one is the Italian Official Nintendo Magazine, while the other is the UNOfficial Nintendo magazine of Australia. Still, 5TH Cell is a 3rd party, not a 1st or 2nd, so their bias shouldn't be THAT strong.
Italian ONM gave it a 9 while Ultimate Nintendo gave it a 10/10. Good deal! You can find the covers to both of these magazines below.
