They are planning it but they are not supporting each and every ERC20 tokens. So, you need to be very careful on what you send to them.
It's more like an exchange wallet where you only can send the tokens listed on specific address.
It won't replace myetherwallet, it won't replace exchange, it won't replace anything.
Yes that's true, but my point here was more trying to understand the next listed coin ( if there will be one).
