Apparently, that would likely be the target and for it to end up replacing ETH, it would mean, there is a huge demand for it more than ETH most especially with the whole smart contract thingy. Also, the market cap will simply must have displaced ETH from its position, but we know we cannot always use that to judge the state as it can change during bull trends anyway. It is a good thing to be picking up ADA at this stage though for anyone who may want to be going long, irrespective of it displacing ETH or not.
