Before we dive into what the speculators are saying, here is SanDisk’s statement on the issue:

“SanDisk periodically has conversations with multiple parties, including Samsung, regarding a variety of potential business opportunities. We evaluate all of these opportunities, but maintain a policy of not commenting on market rumors or speculation.”

So the big rumor SanDisk is talking about is the one where Samsung buys them, and royally screws over Toshiba. If this happens Samsung will be the top dog in flash memory (they’re already close). They will also have their hands on the many patents owned by SanDisk. If this rumor is true this could reshape the flash memory market.
