Historically, during the second phase of a bull run, ETH often outpaces BTC in terms of growth.
That history is based on another token really, the PoW ETH as opposed to DPoS ETH. My feeling is just as the HIVE/STEEM fork demonstrated the broken nature of the DPoS governance we shall see ETH's growth affected by the change from PoW.
Tonight's price is still a little lower than when selling mine off in early summer at $5088CAD, so my guess is that it will not surpass that by Sunday. My guess would be a little over $3600USD, so let's say $3621USD.
