I suspect it will be a whole lot more than that. I'm guessing it will be a fully online solution. All guesses here but:

You will open it in a web browser
It will be login / account based not license based
It will pull data from a server instead of your machine

The questions I'm already pondering is:

Will it require an always on connection or will it work offline?
Will it completely replace Hero Lab or will they work together?
Is it using the same core data?
Will my purchased data flow over to the new tool?
Will it support the creation of custom content (i doubt it wouldn't)
How will custom content be stored? (locally or on a server)
If on a server what will that cost me?
How will player hosted content work (aka community pack)?
Will there be a way for DMs to view / interact with their players character sheets?
Will combat management allow live sync between the DM and players?
How will Realm Works integration work?

Moving to an online solution is a big step and it certainly feels like it's the way of the future. It will no doubt open the tool up to a wealth of new customers. Just going to be very keen to understand the impact of moving to a web based solution as web tools are generally not as powerful as standalone applications.
