Bionic Commando budget was 20mln$ so they lost a lot. if Day1 studios is making movie games then we can assume that 20mln is a lower end of average hd game budget.
The Source i highly doubt those numbers - especially ps360 ones. if game like Bionic Commando have 20mln budget, GTA4 100mln and there's 450-500 dev teams working on a single games(Assassins Creed 2 and Killzone 2) i doubt those numbers.
i would say that first generation 360 multiplatform games(like Burnout 3 or Most Wanted) had 8-10mln budget because many assets were taken from last gen versions. first gen 360 exclusive had probably 15-18mln$ dev budget. now average ps360 multiplatform game have probably 20-25mln$ budget with biggest projects like Assassins Creed 2, Killzone 2, RE5 and GT5 having 45+mln$ dev budgets. if ps360 games are flop selling 1mln copies(Shaun White) then you know that development costs are high.
Ubisoft stated in 2007 that their average ds games have 3mln$ budget and average wii game have 5-6mln$ budget(but those are for whole projects so development and advertisment).
