... I hate these threads. Why would we sticky this thread when the patch comes out and have to skip thru the 5-10 pages of useless crap that's been posted pre-patch to get to the content. How about a thread is made for the latch when the patch comes out?
Also... notch confirmed already that 1.6 will add the new map item and nothing else new at all expect bug fixes.
Nah, I think giants were just implemented in the coding for the shits n giggles. I don't think it's going to be in the actual game. It would be cool if they were a rare mob, and that they would drop valuable items when killed. (thus, for example, meaning the giants would have 5x the health and strength of a regular mob)
I forgot where I saw it, but Notch said the Modding API won't make it for a while because he's afraid it won't satisfy the crowd or be flexible enough for modders.
He's looking into alternatives or other solutions, though.
