Alara Reborn - Spoilers

Today saw our first Alara Reborn preview card (with no rules text) spoiled.
And they've specifically told us to speculate.
So here it is:

Any other speculations?
And they've specifically told us to speculate.
So here it is:

I'll just point out things as I see them:
- Ardent Plea is a Gold card
- It is numbered 1 out of 145 in the Alara Reborn set
- TM & (C) 1993-2009 Wizards of the Coast L.L.C. is now the current signoff for all new MTG products
- Chippy has only been commissioned to do Esper art thus far in this block
- The character in the image seems to be Elspeth Tirel. Her sword, armour and cloak match. Her earrings have changed and her dark hair is uncovered to show Leia-esque buns.
- A Bant looking castle burns in the background while Elspeth is kneeling amongst the ruins of another.
And there are a few schools of thought on this one:
- All of Alara Reborn will be Gold coloured (apart from uncoloured artifacts). If this is the case, this will mean no coloured one mana costed cards can exist.
- Wizards have decided to change the way they number the cards and are putting Gold cards before WUBRG.
- Wizards have decided to change the way they number the cards and are doing the whole set alphabetically.
- Potentially, Elspeth is offering up her sword and/or power to Asha. This might be an offering in the hopes of returning Bant to the glory she remembers.
Any other speculations?
