You can not get minecarts on minecraft pocket edition. Also, minecarts are not planned for the next update.
No, but I heard in the next update it will have Ocelots and Fish, so maybe with the next update, but not now.
no not according to the wiki
Probably in a couple of months but then again most games are up dated not so often as they should
Yes in the next update
they estimated by the begining to middle of this summer
Well the first update was Auto save, the second update is Shears for sheep so that you can't hurt sheep when getting wool, the long awaited Pistons! Skin change! and you have to detonate TNT with either flint and steel or Redstone. Rumors are that the last update might have a system that you can activate mods onto your Minecraft game for Xbox. Thats just a rumor, not a definite update.
