Buy 10 gold chests for 2590 diamonds ... that price seems familiar ...
Buy 10 silver chests for 90,000!
edit: One thing does seem different though - when you select heroes, it seems like you are limited on how many of each type.
edit2: Schedule looks familiar:
5 am reset
9 am merchant reset
12 pm stam merchant
6 pm stam merchant
9 pm stam merchant
10 pm arena awards
Supporting edit #1, it does appear they have the concept of "Threat" in this game. That's pretty cool.
Auto is unlocked at team level 10 or when you've 3 starred a stage. You can use fast forward on stages you've already beaten as well.
Seems like bundles and VIP are very similar.
edit5: took some screenshots. the hero skills seem cool and the combat concepts also seem cool: http://imgur.com/a/thOOV
