He will be, and it will happen eventually. We don't have a date on it yet. He expects the game to be out by the end of the year though, so expect it before then? But he could do it as an addon/extension after the full game is released.
Notch said he wants to replace difficulty with Realism. At one end you will have full realism where you take realistic fall damage, have to eat, must use tools to mine blocks etc. At the other end is creative, where you don't use tools, or take damage, or have to eat etc. In between will be all different levels of realism with different requirements on or off. The more realistic you make the game the harder it will be.
I think we all understand the concepts behind survival mode and creative mode, bluevein. OP was asking when it was coming out, not what it is.
I haven't seen any tweets or blog posts about a solidified date or range of dates where it might be coming out. I just don't think it's top priority right now at Mojangles.
Will the custom slider have the zombie assault mode at the far right?
I hope it's not actually a slider. I'd rather have a bunch of options that can be turned on or off independently of each other. IE., Need to eat and drink, but creeper damage doesn't destroy blocks.
Who knows.
Only Notch.
