exactly unless AOSP/AOKP become part of samsung of affiliated.

really depends on how the marketing guys wanna spin it.
they could let top developers become their affiliate so of course with T&C all their trade secrets remain as trade secrets.

touchwiz will always be standard on every new phone.
then 6 months after the model launch they can make available as online download only via official samsung website the "lite" version.

since they like to rehash their old hardware into new products (Galaxy S -> S Plus -> S Advance -> Ace -> S3 Mini)
it would definitely make their phones faster than running bloatware touchwiz (no wonder they need the fastest processors)

never say never
