I took a look at the Racial Bonus Comparison on Tamriel Foundry that was posted in the News and found it to be pretty useful. I'm not very TES savvy so I've been trying to get a better handle on all these races. I'm not suggesting that anyone should pick their race based on what's thought to be optimal for a role - it's just interesting to the racial bonuses and roles laid out this way. The only gap in the analysis is the lack of info on the Imerpial race bonuses since that's not out yet.
I haven't decided if I'm going tank or healer main this time around, but their analysis pretty much lines up with the role/race combinations I've been considering. With the pre-order giving the ability to cross faction lines (I like to think of it as individuals who disagree with their native factions and leave), it's nice that there's really no bar to picking your preferred combination.
Now, male or female characters this time? Hmmm... So many choices! ;-)
