yes - if you're part of the Pro-Tour you Have to ride the 3 big guns so Discovery has to ride it. It isn't on their schedule yet coz none of the teams have received their "official" invites. Of Course, as the winning team for Lance last year, Discovery has an automatic invite. Also, per Johann, Discovery hasn't really planned anything past May - they do their schedules in 2 segments, Spring and then Summer/Fall. I'm guessing Azevado will be the "leader" this year and I"m also guessing LA Won't ride it this year - taking a rest from all that planning stress (and I'm guessing shhhhhh: hes tired of hearing "thats ALL LA ever does is the TdF so he's proving he can do more than that) Anyway, thats my .02 from a postie/discovery camp follower!
(re: cyclingnews.com.....it has interviews etc and Pro Tour rules there)
and yes: LA has already said he can't ride the Giro at least this year coz of the legal battle with Simeoni
