For me the new upcoming platform is Neblio:

Smart contract platform with token creation capability like Ethereum
Ethereum is looking to become POS, Neblio already is
Ethereum supports 1 programming language, Neblio 8
Neblio supports metadata allowing info to be held within transactions, this is something Eth don't expect to introduce until atleast later this year

The best bit is unlike most of the other platforms who make all these claims of amazing features on their whitepaper with no working proof for years. Neblio has these features already on it's platform. Currently a few ICO's and others are beta testing the wallet (a video by one of the users is available on youtube, search neblio orion wallet)

The crazy thing is Neblio only has a market cap of less than 250m usd. Most competitors who are not as far ahead working product wise are over 1 billion usd marketcap. This thing is going blow soon!!
