Aldmeri have seen quite a lot of attention lately, Are Ebonheart still the most popular faction? Or have Aldmeri taken over the Packs lead?

Skyrim being the most recent game will almost guarantee EP will lead most polls, but my reason for joining the EP is Argonians. Lizard bros unite.

I can't believe that the opinion of those who are interested in the game but don't really follow news development up to launch will change. If they do change then it will be during open beta.

I am certain that it will be the most popular at launch. You have to remember that most people who are on this forum are interested in the Elder Scrolls series. Many of the people who will play have most likely only played Skyrim, maybe Oblivion. So, they will probably flock to the EP because they are familiar with Nords, and lets be honest, Dunmer and Argonians are cooler than most of the other races (at least to people who aren't as familiar with ES lore).
