It literally is FUD. You're basing this and the timeframe on absolutly nothing.
There is no DDoS? Client do not retransmit similar transactions that cause flood? Can you confirm? Are you a developer and very famous with bitcoin client codebase?
Can you confirm there IS DDOS? I didn't think so. It was scammers who apparently did the same thing to gox and bitstamp, and the stupid exchanges got tricked.
