VG247: Blizzard, while currently asking for journalist BattleNet details for the impending StarCraft II beta, said in the mails it sent out to sites yesterday that the test's start date is still off-limits.
"We do not currently have a date to announce for the start of the beta test," said the firm.
It's safe to assume, however, that the beta's very close. And good news was included in the mail: the beta has no NDA.
