Does this move mean AA?

[DOMIT]

I folded a group I to a pre flop reraise today and want to get the group's oppinion on whether the way the betting transpired that my opponent can only have AA in this spot:

Party 25Max NL.. .25/.50 blinds
Folded to mid position,
MP2 raise-opens to $2,
Hero (MP3) raises $5 to make it $7 to go
Villian (on button if I recall correctly) raises to $25 straight

The $25 straight covered both me and MP2.. i.e., if we're to call, we're having to call all-in.

The only hand that I could put him on was AA. I don't see him doing this w/ KK, or other.

Let me know what you think.
