As someone who is also anxiously waiting to hear from Cornell (my status didn't even update!) I thought I'd chime in on a couple of things.
As far as UVA having already filled up its class - Most likely true, I'm sorry to say. My friend who is waitlisted there visited and talked to Jason Trujillo (however you spell his name) at UVA and he told him that 75-80% of the seats were already filled - and this was more than a month ago. Hopefully some of you still waiting slip in, but it is looking a bit bleak at this point unless you have a fabulous app.
Regarding WCLegal getting T-14 waitlists, on the surface, yes it seems a bit incredulous. And not knocking WCLegal, as I don't know anything about his/her app, but it very well could be your personal statements/writing sample/etc. With those numbers from an Ivy and soft factors, it would seem that supplemental written materials could have been a big factor. The importance of them is always understated. From my experience: My ex-gf and I went to a top undergrad like WCLegal. Her numbers were 3.7 (graduated w/ honors) in International Studies, 168, soft factors included study abroad at Oxford and part-time work all through college. The only T-14s she applied to, Columbia, UVA, and GULC, all waitlisted her (she eventually got in off the GULC priority waitlist.) I have a 3.37 (same major) and a 170, without any soft factors. This yr, I was admitted to GULC less than 3 weeks after I applied and currently waiting to hear back from Cornell and Penn. She was clearly a stronger candidate than I was - my verdict? When she gave me her PS to read while I was applying this cycle - it was GODAWFUL. I sh*t you not, one of the most bland, incoherent, and unintriguing things I had ever read. Not to toot my own horn, I was a Writing Minor in undergrad and have won many awards for my writing (and presumably wrote a better PS than my ex.) Make what you want of it. In the end, I believe that the PS and other written supplements are extremely important.
