It's a sensible release imo - got to remember that although it's the A900 that gets all the attention on the LL forums the vast majorities of Alpha DSLRs, and the reason Sony's number 1 in some countries and a distinct (if distant) 3rd worldwide is because of the A100-A700 range.
First thing to note is that 4 out of these 6 lenses are going to be seriously cheap. We've got plastic mounts and micro-motors across these 4 - this is why we've got a new 55-200 - it's got a micromotor in it instead of the old screwdrive. They could be SSM motors, but I doubt it - Sony's always marketed its SSM lenses before and apparantly adding an SSM motor to a lens requires a re-design - you can't just shovel one in.
50 1.8 makes sense to me for the reasons lattiboy gave - you at the cost of irritating the a900 users you give the APS-C users a significant cost saving.
It's more of a shame that the 30 macro is APS-C only - could have done with that on FF. Why's it a macro instead of an f2? 2 birds with one stone - if it's sharp from wide open you won't miss that stop too much, the AF should be ok due to the low weight of glass and the macro capability will appeal. Could well be 1:2 instead of 1:1 which would boost the walkaroundability even more.
New kit lens - old one was getting panned. New 55-200 - micro-motor. Lets sony do a D40 on us - hopefully not too soon though because the lenses are still lacking.
28-75 is disappointing merely due to the micro-motor, a lens like this should get an SSM motor. Still, it forms a 3-way choice for Sony users. Sony -> Sigma -> Zeiss - hopefully 3 distinct price brackets with clear advantages each time you go up a rung.
Super-tele - great. 500/4 sounds sensible - it's long.
Lack of Zeiss? Biogons - I think you've spent too long looking for black helicopters. Sony put out 4 ultra-budget lenses, a mid-range lens and a lens that's squarely in 'G' territory (Sony uses the G brand for their telephotos) and you're concerned that there's no Zeiss? There's no 24-105/4 G SSM either, maybe this means that the a900 is being abandoned... Give it a couple more rounds of releases, if there's still no Zeiss you might be on to something.
Good stuff Sony, keep it coming. Some kind of mid-range portrait prime, 24-105/4 and Zeiss 24/2 before too long please. And the 400/4.5 could create a cult following if you get it out soon - kind of like a Canon 400/4 DO but with fewer downsides.
