It really depends where you're at in the market. Apple and Google are on the attack and RIM is nervously awaiting the siege. If they can't ship they need to at least rally the troops and preach to the faithful. I'm guessing RIM did enough market research to understand that there is a major risk of users/developers jumping ship even in the next 6 months.
Alternatively, RIM are perfectly secure in their castle - there's little sign of any movement in their core corporate market to alternate devices. No need for them to panic, they want to do this right.
When I commute to work in the morning, and they announce the train is delayed (again!) out come 500 BlackBerries... It's quite a sight!
