According to looprumors.com
"We received word that two large shipments of Power PC 970 processors went to Foxconn in Taiwan, under a purchase order from Apple computer. Twenty thousand 1.4Ghz PPC 970's and forty thousand 1.6Ghz PPC 970's have already arrived in their hands. IBM's inventory contains fifty thousand 1.8 Ghz PPC 970's, of which forty thousand are destined for Foxconn tomorrow (Wednesday).
IBM has listed as pending 2Ghz parts as well, which means that it will be in inventory within a month if their fab in East Fishkill produces sufficient volume of them, and from what we hear they should be in stock by mid-June. Apple has stated that they need a minimum of 40 thousand in order to make a production run, and from what we understand this is for dual processors because normally their production runs are twenty thousand units. It is not IBM's policy to comment on other vendor's unreleased products. We have also been briefed that the PPC 970 will come in 2.3 and 2.5Ghz configurations by the end of the year, and as well some preliminary specs on the upcoming 980 processor, which is a Power 5 derivative."
