GS is probably right on capital spending slowing in the first half of the year. What they aren't taking into account is that the smaller s/w companies that will be even more attractive for takeovers. Ellison and Oracle, and other companies, are in great shape financially and can wait for the stock pricing of companies to continue to fall and then offer a premium of 33% or so.
Informatica is fairly priced at its current PE trailing and forward.levels. If it continues to drop, the chances of an offer are going up. I would expect an offer between $20 and $21 in Dec.
