Intamin has always been interesting to me...but they really haven't built a Giga since I305 I believe
Where as B&M has built Orion, Leviathan, and Fury since then
Not to say they will *never* do it again, but if BGT were to get a Giga I assume it would be B&M...and probably the world's shortest Giga
Unless they struck some deal where SWO tests out the prototype for the Surf and BGT gets some kind of discount Giga lol
