Jazwares is also making Mortal Kombat figures - but so far they don't look like they compare to the Street Fighter Figures.
Ermacs green eyes aren't doing it for me. BBTS needs to update there listing to now show this as a 6 pack

the generic robots look pretty good.

But so far that looks like that is all there is for this line. Just 2 multipacks for this line. Hopefully we will get some cool 2 packs for this line up like in the Street Fighter line.Just saw this listing at BBTS:

1x Sub-Zero
1x Scorpion
1x Reptile
1x Raiden
1x Baraka

1x Johnny Cage
1x Jax
1x Sub-Zero
Maybe if I have time later I might call their customer service to see if I can get any more details on this line and/or availability
update:
I emailed them this: I was just curious if you had pricing and availability information for your Mortal Kombat 4 inch action figure line. Which stores will be carrying them - and when do you expect them to be out?
and they responded with this:
Thank you for contacting Jazwares, Inc. and for your interest in our products. We do not sell any of our items from our website or from our office. Please check with your local Toys R Us, Spencer, Barnes and Noble and Target stores.
