there isn't even a question, the S58 comes from the factory 500hp and B48, B58 have all shown improvements in tuning potential over x55 engines.
Stage 2 tuned B48/B58s are doing 4.5s and 3.6s 0-60 respectively, I would bet my money that when Bm3 cracks the S58 is supercar territory performer with full catless dp, intake and catback exhaust.
My guess is 650bhp on stock turbos after tuning, based on seeing what the B58 supra can do tuned with a single turbo.
