What happens between now and then may be greatly influenced by news $30M spending will proceed on Ethereum infrastructure by concerned parties going forward. Tentatively, an increase is likely, hovering somewhere between today's price and the extreme presented, reaching a peak somewhere on the timeline.
As to whether a new higher high will occur, solidifying Ether's USD valuation here on the digital currency 'backside' as a hedge against a possible late May BTC correction, and other factors of in the market, is speculative.
Ether has retained a good portion of its latest surging increase in BTC valuation following BTC's fabulous rise. And on the USD side did well during the mini-correction. It may be relevant to point out if digital currencies are to gain from their intrinsic value they will have to compete on market capitalization with the very currency which drags their present valuation all over the map; this may mean investors will benefit from Ether swallowing not just the tail of the whale, but a good portion of its body, making way for its intrinsic valued cousins to refresh the sea with services and economic opportunity by way of active developer and user communities, subsuming their progenitor for the good of all.
If the whales are worried at all, investors in Ether may not see it unless they first present the challenge. It will otherwise probably be business as usual, which isn't bad, but doesn't really seem to deliver on the widespread promise of systemic change resulting in lower fees, greater access, and, as mentioned above, new economic landscapes carved out of information in cyberspace, the virtual and limitless real estate which continues to capture our imagination and innovation.
