Remember that it's possible Kaiden is remembered by a crater on Virmire.
If Miranda gets shunted to 'background character' the game would be missing a sentinal NPC; arguably that isn't too much of a point, as there wasn't a clearly defined 'soldier' class (I believe it's stated at one point Jacob is a vanguard) however the are clearly characters (Zaeed, Grunt and even Legion if you know what you're doing) that can fill the role.
So meandering back to the point I made in the first place; unless you saved Alenko you wouldn't have a sentinal npc, something that could potentially be very damaging to squad dynamics.
Sure, it's possible that they could lob in a brand new sentinal NPC, however if Miranda survived... why? We have Miranda.
Edit: the picture's a screencap of Blur's trailer.
