They already are when they implied it was outside their control...
If Sony US wont allow it be then post the proof... cause right now Sony EU/UK is letting companies release games that does not contain a dub outside of the original language. And Sony US looks to be letting Yakuza 3 out on disc without a dub.
If they feel that it is outside their scope to press X number of BD copies cause they feel they cant sell that many... well say so.
I know Arksys isnt big but I have a hard time swallowing the line that Sony US is saying no to a disc release. So far 2 of the 3 games that are being released sub only are being released as DL only... both by Arksys.
Looks to me like it's a management decision to do it cause the numbers dont make sense...
