Seeker/ promethean super suit would be cool in halo 5 and 6 campaign...

As you can tell the seeker has no picture so 343 has all creative rights to the design of it. Its the newer more advanced model of the war sphinx. If this appears in the campaign then i would like to see the war sphinx by itself once then have 2 combine(read halonation) to make 1 huge one in the halo 5 campaign. then!! introduce the seeker in halo 6 as a badass fighting machine that is superior to the war sphinx in every way. --- atleast thats how i would plan it out.......
