I prefer the *^ syntax because:
1. ^^ looks like we a re including a new logical xor syntax
2. *^ has the asterix from the multiplication syntax while using the caret from the mathematical exponentiation syntax. Exponent is a kind of multiplication, with a default identity of 1.

Also if this feature does get included then the code:

a *^ b *^ c

should be evaluated as

a *^ (b *^ c)

not

(a *^ b) *^ c
