I would probably read this in the opposite direction. All of the points you mark in favor of twitter are similarly true for facebook (they have more competition, but are pulling away in most important demographics.) The difference is that facebook can create a twitter competitor themselves and with their chat system have already shown that they know how to handle messaging, while twitter is nowhere close to getting into facebook's turf. The dangerous point about waiting for someone to sweeten an offer is that they probably have some internal "how much would it cost us to do this ourselves and just crush them" numbers to look at as well.
