Foo Fighters and BlackBerry 10

When the BlackBerry PlayBook came out, RIM did some videos with the Foo Fighters talking about it, and also in the BlackBerry World in 2011 appeared Will.i.am playing with the PB. So my query is, if they (Foo Fighters and Will.i.am) still use BlackBerry, why RIM doesn't meet them to talk about BB10, or why they don't create buzz around BB10 like the owner of Def Jam did the other day.
