Are there only three ASICs due soon? I was under the impression there were a few more initiatives.
There are more initiatives (in alphabetic order):
1. The most known is ASICminer: https://bitcointalksearch.org/topic/asicminer-entering-the-future-of-asic-mining-by-inventing-it-99497
It is coming quite soon, but the shares of the mine are all sold.
2. New product of Bitfury: https://bitcointalksearch.org/topic/picostocks-100ths-bitcoin-mine-100th-140366
Coming June-July, late but the parameters/price are interesting, IPO of the shares of the mine just started (01.31-02.14).
3. DeepBit Reclaimer: https://bitcointalksearch.org/topic/dbrclmr-deepbit-reclaimer-asics-108375
Probably some troubles, they are investigating at the moment if they'll continue: https://bitcointalksearch.org/topic/deepbit-reclaimer-asic-prepare-refunds-139089
