Will sking regress before it progresses?

Hey
Before you read this I want to let you know why made a seperate post form others; to get my veiws across and get some imput on this situation.  I'm not 100% uo to date on everything in the industry so add to anything I missed or correct me. Thanks.

I was looking around NS earlier today and I saw Cj's post titled "rails, what's all hte hype about" and began to read everyones views on sking.  The majority of people seem to enjoy slaying rails because they think there is still a lot of progressing to be had.  While others say that there isn't any.  So I looked at both sides. 



With jumps and big air we are running out of places to grab a names for new grabs.  Also I think the sport has reached it's limit to spinning.  Tj's 1440 was huge and pretty good looking.  Then we have the 90 degree left 270 right spin by.. well I forget, this is what I meany by I'm not 100% up on the sport (sorry for those yelling at the screen).  Then we have the corks and the flips, and bios, and so much more.  Is there really much more we can come up with?  I guess a bit but not that much more.

Then there are rails.  A fair amount of people cna do 450's on and even more can do 270's on.  I am not one of them.  Spinning onto rails can get bigger than it is now I could think.  Then you can throw in combo's onto rails like butters or flips or spins and grabs etc which haven't maxed out by any means yet.  And I do know some of this stuff can't be possible ie double flips... that is to say, not possible just yet.  I'd say 75% of the ski population can or have at one point grinded their way down a rail, regardless of the length or difficulty.  Then there is the 25% who haven't yet tried or are not looking at a rail again (my catigeory).    So as far as rails go there is a lot more progression.

So this leads me to the question where will sking go?  In terms of jumps and stuff will it progress back to small spins to make everything look super smooth and stylish? Or will we continue to push it to a 1620 or a 1800 if our bones can handle the landing?  Will rails progress as much as jumps have been?

I'm not sure how much you guys have though of this but I have for a bit now.  Where I stand I have a lot of progression to do, but from the headlines and the talk here on NS I seem to think people are reaching a limit.  Will there be an explosion of progression this year in the industry or will we regress to polish stuff up?  Thanks for reading.  Sorry if some of my facts are wrong, just wanted to get that out there and read what you have to say.
Cheers,
