Well we already know about this one:
But now it lacks the pink buttons and ball-top, yet it still sports the odd button placement from before:
/\ O L1
 X R1
It has the L2, R2, Select, Start buttons on the top, along with the PlayStation button to bring up the XMB.
And here’s the new Hori…Fighting Stick 3. --;;
It features the standard Hori button placment of:
L1  /\ R1
L2 X O R2
Except, instead of the L buttons being placed in the corner, the R buttons are now in the corner.
The HFS3 has the L3, R3, Start, Select and Turbo button / switch on the top, why it doesn’t have the PlayStation button is beyond me.
So there you have it, the first batch of commercial arcade sticks for the PS3, whether or not they use Sanwa or Seimitsu remains to be seen (probably not, well maybe for the Virtua Stick HG, signs are unlikely though).
VSHG hits in Feb 07, whereas the HFS3 hits in Jan 07.
