In all honesty I think you might have missed some of the shots in this trailer. I'll agree most of the backcountry shots are your average backcountry skiing, its kind of hard to progress backcountry as quickly as park and urban since you have to be careful of the terrain you are skiing due to natural hazards. That being said the rock jib to underflip (I think) was super creative.
I think level 1 is trying to shy away from the whole spin to win trend and get into more creative features, this could be why you think they are not bringing anything new. Where else have you seen a flat 1 or a 15 foot drop to wallride out? I know the quarter pipe jump thing (at 1:08) has been done before but you don't see features like that all the time or people going that big off of them.
The urban in this trailer is pretty crazy, once again I see level 1 being more creative with the features instead of just having people huck bigger and bigger tricks, like it has been stated above Ahmets 270 then riding out switch on the stairs was pretty different from most things I have seen. There was also gapping the walkway to a down rail, it may be similar to some of the down rails seen in park shoots from realtime but its so much gnarlier in an urban environment. The wallride at 1:47 seemed to have a huge drop off of it at the end probably nearing 20 feet, thats pretty high for such a small landing. The gap to tapping the garbage bin was pretty sick imho but some people may not like that style. The sun valley jump may not have a much bigger gap then in previous years but they get so much much air and it looks like its pretty kicky for a jump that size. And the last rodeo to complete flat has huge, that shit takes serious guts.
Its cool if you don't like the trailer, not everyone has too but saying that it does not show progression is a bit ignorant, people don't have to be spinning 1800's to show progression, being creative is a better way than spin to win in my opinion.
