Fortunately I just upgraded to Verizon's premier new 300mb/sec.

Unfortunately with everyone bombarding the server at once, it's not going to be distributed at any speed near that.

I'm willing to bet that the best speeds people are going to get are around 300k/sec on launch day. Fortunately those with legacy will already have most if it and will be seeding while they download the small patch on launch day, helping make it faster for those that have to download it all.
