If they keep the upgrade system employed in ME2, then I think that it would be cool if at certain points you could branch off and do different upgrades sort of like a fully evolved power. Also as some of you have said they could make attachments such as scopes be stand alone upgrades for any weapon that could be outfitted with said attachments.
