Except there are plenty of minecraft users that haven't indulge in the type of value that mods add.
My 6 year old son loves Minecraft and part of that love involves watching about the mods on Youtube (I am forced to watch it with him because I have to cull through the ones with bad language). But he can't participate.
Updating the graphics, new gameplay features, incorporating some of features of the most loved mods and/or tools that makes it easier for the masses to participate in what minecraft is all about is worth a Minecraft 2 label.
I do think it would be a bad ideal for MS to lock MC behind Windows and the Xbox. Its not like they have to do so. It might be a better play to lock it behind their cloud platform versus their hardware. Universal and portable saves that migrate to any platform would seem to better serve their best interest as well as MC fans.
One Minecraft for multiple platforms would be a good way to endear fans. I haven't checked lately but my son says MC on the 360, iOS and PC aren't the same game as features are platform dependent.
I use this setting for my son, it helpst a bit: https://support.google.com/youtube/answer/174084?hl=en
My son looks at YT as well, sometimes he plays Minecraft and his father has to spend time off work, doing work getting the mods to work
Imho, Notch has not in anyway milked Minecraft the way it could have been done, not that MS would do that, but imho, there is plenty of unexplored ways to get more money from Minecraft.
What i just don't get is, that Notch has so much money now, and since he so far has avoided the "money hats" of low hanging fruits i simply don't understand what has changed.
