I've seen it first hand, only on the LF right now, as it's not showing during national programming for some reason (megamanfan, have you seen it during national?). Here are my initial observations (it's slightly different than the TWCT pics I posted):
1) There is animation, which I like. The LDL animated in... the tabs animate, and glow when the tab which is meant to be in focus moves left.
2) The Local Ad Crawl is nicer, with smaller font, and, surprisingly, I really like how it looks. I hope the watch/warn/advisory crawls aver very similar.
3) The time AND temp are now shown on the bar at the same time.
4) The data animates downwards, like the Satellite HD LDL.
5) It seems the monthly precip isn't showing during the LF for some reason. That's a bug I'll have to report.
6) The icons really need to be larger.
7) The pressure indicator has been fixed! No more tiny arrows you can't see.
And, as stated, it doesn't match the current LF look that well, but, it's a GREAT improvement, IMO.
