Ummh... I don't think so.
The M7i/M10i will support 4x STM-1/OC-3 ports or a 1x
STM-4/OC-12 port in a single slot. The STM-16/OC-48 quad-
width PIC is no longer supported, particularly on the new
Enhanced CFEB.
The ASR1000 will support up to 8x STM-1/OC-3 ports, 8x
STM-4/OC-12 and up to 4x STM-16/OC-48 ports per slot.

There are two models of the ASR1002.
The ASR1002-F has a fixed ESP (Embedded Services Processor)
rated at 2.5Gbps.
The ASR1002 (modular ESP) supports both a 5Gbps and 10Gbps
ESP. The 10Gbps Ethernet and STM-64/OC-192 will work in this
chassis.

The ASR1002 can do quite a couple of things. One can use it
as an edge box for relatively high density Ethernet 802.1Q
aggregation (remember, it has 4x on-board Gig-E ports, and
3x slots to spare), or even high density SONET/SDH
aggregation.
There is talk of up'ing the control plane memory on the RP
(Route Processor) to some "ridiculous" figure. If that
happens, you're looking at a decent route reflector (which
would be cool on the ASR1002-F since you're likely not going
to be forwarding any user traffic through your route
reflector).

Of course. The next best thing after the M10i is the M120.
The M40e is pretty cool, but its lack of 10Gbps support just
make it easier to jump from the M10i straight to the M120 -
in our case, at least.
But that's not the space we're looking at. We're looking at
something that's fairly small-to-medium sized, is fairly
dense both in terms of Ethernet and SONET/SDH, supports only
centralized forwarding to keep things cheap, and costs
reasonably for the performance.

This goes both ways. But many times, it's not always about
the money. Even if I could get Juniper to sell me an M320 at
the price of an ASR1006, I wouldn't want one if one of the
reasons I needed the form factor of an ASR1006 was because I
have space constraints.
There's a number of factors that play in, not (always) just
price.

The 7206-VXR is definitely cheaper than both of them, and
just as underpowered. I've been able to forward up to
950Mbps aggregated through an NPE-G2 acting as a small core
router @ some 85% CPU utilization. As an edge router, I've
brought one close to 900Mbps at 90% CPU utilization.
No packet loss in both scenarios, but very little fish-head
room for any nasties.
I wouldn't use this platform anywhere I thought a hardware-
based router, however small, would be more useful.
Cheers,
Mark.
