I'd like to see the ASR9K to run out of steam :)
Still haven't seen the preso on 9904 internals but I'm not quite convinced. Do I read it right it's just basically 9006-2 with some RU savings?

But MX104 can't hold the full internet routing table in forwarding-table so it's good only for peering or can it indeed?

I think MX104 can be a nice small town PE to aggregate the town ring so no competition to MX480/960
