I guess 600-800 area is valid for Ethereum for May, personally, I do not think it will go over 1000 quickly, they need to solve wallet issues with exchanges and have a soft fork Byzantium upgrade, after segwit in BTC ethereum based coin transfer fees are similar with Ethereum. Also, Ethereum platform needs powerful coins like EOS to dominate the market.
We already made the first move above $700, so I believe we should be able to go test the $1000 to $1200 region pretty soon when the whole rally starts breaking out. A small correction is going on a little bit in the whole market right now, so it would actually be good to wait it out and see how things end up unfolding in a matter of time.
EOS on the other hand has really been going nonstop for a while now and it is still looking unstoppable. Looking forward to how the whole market ends up playing out by next week.
