There has been a couple. But they are just regurgitating Overview Trailer info and the information from the JP site.
Some even lambasted when they couldn't answer questions about the game...proving they hadn't actually played it and were deflecting big time. Amateur hour indeed.
I don't think we will see any "real" reviews until after Monday.
I'm fully aware of that, even mentioned it earlier in the thread. However, the only Metroid game that went with Giger's style before was Super Metroid.
