Yes, the price of ETH's marketcap will go over that of bitcoins very soon(possibly even today or this week).

The price has been surging and for a good reason. ETH has an upgrade in their code coming out within the next few weeks. The price is going up now because people are pricing in the expectation of ETH releasing their new version soon.

When the new version is released it will likely go even higher. There is also another version upgrade to be released sometime in 2018. Their roadmap is clear and more precise, vs bitcoin who has a bunch of Jihan Wu drama.
