Interesting published(the paper is somewhat older, but i now have a linkable location) by Gartner - "Oracle's New Sun Support Policy May Disrupt the Hardware Maintenance Market":
These changes are significant and affect every Sun customer. Oracle is offering high-end support at up to 50% below the current market rate to attract users who defected to third-party maintainers (TPMs). This bold and aggressive policy has the potential to shape the market, because it will exert considerable pressure on TPMs that actively canvassed the Sun installed base after the acquisition was announced. Simplified support pricing in effect reduces choice and may polarize customer opinion despite the value of their offering.
