After talking with Smithmeg and DTAD a bit, we've got enough data for some Projected Stats on the Warpriest of Vandria. These are not official, confirmed stats. But I believe these aren't very far off, either.
Assuming the build is an Elf (Vandria is a racial deity), with Fighter 2/Cleric 5 (Searing Light helps us determine this)/Warpriest 3 (We can assume this due to the Mass CLW) being the class distribution. It fits the printed stats, including the +11/+6 melee attack if we assume an Str of 14 (sensible) and a +1 weapon being used (also sensible). DTAD suggests it could be Ranger 2 instead of Fighter 2 "because he's probably an elf", but this doesn't throw off our numbers very much. Could be possible.
Warpriest of Vandria - Projected Stats (40 Points)
Chaotic Good
Commander 4
Level: 10
Speed: 6 (or 4)
AC: 17 (Could be anywhere in the 16 to 20 range)
HP: 55
Type: Elf
Melee Attack: +11/+6 (10 Magic)
Ranged Attack: None (Wouldn't be printed on card. This is for completeness' sake.)
Commander Effect: Followers that have a ranged attack gain Sidestep.
Special Abilities:
Sidestep
Single Combatant (This creature gains +4 AC when adjacent to only one enemy)

There may be additional castings of Searing Light or Cat's Grace, but I'm unsure. Either way, the above is a fairly good mock-up of what he'll look like, I think.
