As far as I know, there's no dedicated site for it yet (at least not in english). Mizuumi might pick it up, but they'll probably be more focused on MBAACC, Aquapazza, and Skullgirls (together with dustloop), at least in the short-term.
Btw, if people are curious about system mechanics, here's what was posted by umgogo on SRK (this is back from last july, so some of it might've changed):
[spoiler]
Miscellaneous information
The Chaos Gauge (Super meter) can hold up to three stocks at any time.
A dizzy meter is present, as in Street Fighter 3 series and King of Fighters XI.
Before each battle, you must "select your bounce", i.e. choose between the Step (dash) and Run abilities. The Step can be cancelled into (attack -> Step), thereby eliminating some recovery time, while the Run can be cancelled from (Run -> attack or High Jump), allowing a character to move in on the opponent more easily.
Next, you are given your choice of two Extra moves out of a total of four. Each character has two Extra special moves and two Extra Ultimate Chaos moves (Level 1 Super moves) to choose from.
Movement/defensive system overview
Step/Run (selectable)
f, f (hold f to run)
Backdash
b, b
High Jump
db/d/df, ub/u/uf or run, ub/u/uf
High Jump cancel
Cancellable normal moves (but not special moves) and the Run may be cancelled into a high jump.
Air dash
f, f (in the air)
Double jump
ub/u/uf (in the air)
Roll
AB/f+AB/b+AB
Ground ukemi (recovery roll)
AB (when about to touch the ground)
Aerial ukemi (air recovery)
direction + AB when launched into the air
Tactical Guard
CD (requires half a stock of Chaos Gauge; can be done in the air)
If your character absorbs an attack, he/she will automatically counterattack.
Offensive system overview
A = weak punch
B = weak kick
C = strong punch
D = strong kick
Chaos Combo
Normal moves can be chained together as per this flowchart:
A -> B -> C -> D
Throw
AC
Throw escape
C (just before being thrown)
Counter Hit
A Counter Hit will yield longer hit stun than a normal hit, allowing additional attacks to connect. For example, a sweep cannot be followed up by anything on a normal hit, but can on a Counter Hit.
Guard Break Attack
f+CD (requires one stock of Chaos Gauge)
This move will break an opponent’s guard and can be cancelled into from normal moves.
EX special move
special move motion +AC/BD (requires half a stock of Chaos Gauge)
Not every special move has an EX version, and none of the Extra special moves does.
Ultimate Chaos/Extra Ultimate Chaos (Level 1 Super move)
motion + one button (requires one stock of Chaos Gauge)
Destruction Chaos (Level 3 Super move)
qcf, hcb/qcb, hcf+AC (requires three stocks of Chaos Gauge; cannot be done during Exceed Chaos)
Chaos Cancel (Super Cancel)
special move -> Ultimate Chaos (requires one extra stock of Chaos Gauge for a total of two stocks)
Chaos Shift
AB/f+AB during Ultimate Chaos (requires one extra stock of Chaos Gauge for a total of two stocks)
An Ultimate Chaos move can be cancelled into a special form of movement as an escape tactic or to allow for follow-up attacks.
Exceed Chaos
BC (requires three stocks of Chaos Gauge; can be cancelled into from normal and special moves)
Upon the activation of Exceed Chaos, the Chaos Gauge begins to drain until it reaches zero. EC carries several benefits:
1) The dizzy meter empties instantly
2) Gradual life recovery
3) All attacks become cancellable
4) All moves which use Chaos Gauge consume a portion of the timer, the amount corresponding to their normal gauge cost (allowing for otherwise impossible combos, such as special move -> Chaos Cancel into Ultimate Chaos -> Chaos Shift into normal move -> Ultimate Chaos or EX special move…)[/spoiler]

Catherine dons a witch's robes and holds out an apple. If the opponent attacks him, he summons a large mirror and slips into a queen's (?) dress. The image of a beautiful princess appears in the mirror, and Catherine throws the apple through it and at the opponent.
This move is an obvious reference to the most well-known plot points in the tale of Snow White - an old crone offers the heroine a poisoned apple, and a mirror tells the evil queen that Snow White - and not the queen - is the fairest in the land.
