Maybe the email i got that said i should wait to buy a S5 hash board maybe they are were watching out for me i don't really have any thing against them. just got a little errts off how it was done.

There's a bit of a filip in BTC price on, so ya'all looking to get some of these better be quick before bitmain put the price up!

It was surprising when it rose from $320 to $340, then even more surprising when it rose from $340 to $360. But who'd have thought they'd raise it again from $360 to $378? It has to be noted here that the latter two price rises were parallel to rises in BTC value of similar magnitude to the one being currently experienced.
And don't forget, bitmain have no shame at all in changing (raising) the price several times in a matter of hours .... let alone any bigger timespan. So take to your confort zone of believing they are in the so called happy place on your own (and at your peril!).

He's right, the S5 price very roughly tracks the exchange rate so it could be adjusted at any time.

Very possible...

They can ram it up there A** were the sun don't shine !

BITMAIN YOU GUYS ARE NOTHING BUT A BUNCH OF CROOKS MILKING THE COW !

but looks like they still have sales https://blockchain.info/charts/balance?timespan=30days&showDataPoints=false&daysAverageString=1&show_header=true&scale=0&address=1KwA4fS4uVuCNjCtMivE7m5ATbv93UZg8V

some of the 2000 still for sale?   

bitmain are a real business and they have their numbers worked out pretty well (or have some good brains behind their money), so if you want to make any analysis on their possible move(s) it better be based on empirical evidence (not an un-informed hunch) or sound business logic (even both plus many others!). Unlike some bitcoin chip fabricating ventures, they seem to have got some kind of balance and (presumably) use the home mining market as an outlet for the gear they need to decomission (or as a testbed) as clearly it is more profitable by magnitudes to self mine.
Anyway, your memory probably let you down on this one as bitmain have previously raised the price (of the S5 no other ...) more than once in a single day.
