Official Update on 360 Community Rosters.
Guys, wanted to give you an update on when Version 1 the 360 Community Rosters (please see below on "versions") will be available. Roughly speaking, we expect them to be available:
Thursday, July 15, Mid-Day.
When they are for sure up I will post the Gamertags they will be available on below. As a few more of us get them, we'll mirror them on a few Gamertags. Thanks for your patience. Please no 360 friend requests though! You can download them without it.
Regarding Versions: This is the First Version (1.0) is the first set of the rosters. Obviously a lot of people are anxious to get their dynasties started and we wanted to get a set out as soon as possible. We made an attempt to include as many corrections as we could, but simply put: not all will be included. Carson's post a few down explains this well: if you a "less hardcore" dynasty player who wants to start now, these are for you, but they should not be considered a "final product" as there still needs to be things changed, updated, etc. Please understand that we are working our hardest to get a good version out, but in order to have a really truly "final" version we will need a lot more time. Because of this, Version 1.0 is a good starting point.
