Looking at the high res. interior photos, I do not see any type of latch or hinge. Therefore I have to conclude that the rear quarter windows are fixed. Another improvement is the trunk volume increased to 12.3 cu ft (was 10.9 cu ft.) Interior volume appears to be larger too. C&D says 86 cu. ft. HR says 96 cu ft. The HR # appears to be really huge, so I'd guess they got it wrong. The 99-04 has 83 cu ft of interior room so 86 cu ft. for the 2005 sounds more believable. I actually hope the interior is not a huge amount larger as you'll lose some of that sporty car feel.
