What does the new "iModel 2.0" platform mean for v1 i-models, and the i-model file format?

Hello,

I am looking for clarification of what the new iModel 2.0 platform, announced here: https://www.bentley.com/en/about-us/news/2017/october/11/bentley-imodelhub, means for the i-model file format.

Does this mean that there will be anew version of i-model files?

If there is, does that mean that there will be an update to the v1 i-model Desktop SDK, or another SDK, or no SDK support?

Can we expect v1 i-model files to be compatible or convertible with a potential new version?

Any clarification would be helpful.
