Here is the physical version that I bought. I have downloaded, played stress tests and will have headstart access. I also get the heros band. They sent me a code the day after I pre-ordered the game and been in stress tests ever since. I think your info is a bit wrong.

It's also worth noting that the physical version of the Standard Edition of Guild Wars 2 is available on Amazon for $30. (For the gamers that prefer physical copies.) It's just the Standard Edition though, not the Heroic Edition. http://www.amazon.com/gp/aw/d/B001TOQ8X4/ref=mp_s_a_1_2?qid=1386011176&sr=8-2&pi=AC_SX110_SY165_QL70
