We at Light Reading don't know of any 35th birthday parties going on. Maybe at this age, Ethernet would prefer to stay at home with a good book. But if you want a bit of recent nostalgia on the topic, here's a writeup from Ethernet's 30th birthday, with bold predictions about 40 Gbit/s.
You could also read an extensive interview with Metcalfe from 2005, or see this discussion on Terabit Ethernet.
