An authoritative answer to your question requires access to and revelation of "insider" as well as "forward looking" information...both of which are forbidden on this site. Rather, all that can be said is individual opinion and theory. But, based on how things have migrated with BB10, my opinion is that the answer is no.
Note, please, that there is a vast difference in pricing in different regions of the world. For example, in my country, a BIS plan costs significantly more than the non-BIS plans, making BB10 devices much more affordable (from the monthly cost perspective) than legacy devices that required BIS.
Occam's Razor nearly always applies when troubleshooting technology issues!
