Wizards of the Coast have announced the winner of the war on Mirrodin and the name the real name of "Action".
Welcome ladies and gentlemen to New Phyrexia
It would seem that I was right (lucky then that my analysis was the previous post :p )
I said that they would move Infect into all the colours. They said this week that there would be Red infect cards, and all but one of the colours would have access to Proliferate. A version of the Sword of War and Peace has been shown. It's not an official spoiler, so I won't reveal the whole card, but the White ability is said to be give a +1/+1 counter to target creature, which would have the side effect of being able to heal -1/-1 counters as well. This, to me, seems in line with it being a tool of the resistance, to stave of infection.
Not only are the Preators revealed in this set, but it looks like they are getting cards. The two spoiled so far suggest that they are a cycle of Legends, one for each colour, with a static ability that buffs your creatures and a second static ability that debuffs your opponents creatures. If nothing else, they will probably make awesome mono-coloured EDH/Commander generals.
The major theme of the White cards in the set (the Phyrexian aligned ones at least), is the new religion of that faction, which Suture Priest is a part of. No mention of what the Pristine Talisman is about thematically, at least not yet. They do however say that there is a resistance movement, that still hold a small fraction of the territories available.
This post is largely self-congratulatory, but we all need one of those every now and then :D
