Next Sony Ericsson announcement on May 28th?

The above is from a document at the FCC requesting confidentiality for the DS200 bluetooth headset. I posted about this headset 2 days ago. A member at Esato pointed out that the date might be an indication for the next SE announcement. If this true and this headset is to be announced then it probably won't be alone. May 28th...let the countdown begin...
