We got our stack of EX3300s yesterday.
I can confirm that (with 11.4R2.14 at least) you can do mixed 1/10GbE on the 
EX3300.
I've got 3 in a VC ring of 10Gb using ports 2 and 3, 10GbE in port 0, and 1GbE 
in port 1. Didn't have to do anything special either, although I did tell the 
VC to use ports 2 and 3 which was probably unnecessary.
1GbE SFPs cause a ge-x/1/x interface to appear, and 10GbE SFPs cause an 
xe-x/1/x interface to appear.
