This looks awesome!
10MP with built in IS!!!!! Schweeeeeeeeet 
So.. what's with the "alpha" lens mount.. I read the blurb and could not really discern if this means that the new and upcoming Sonoltas will or won't accept Minolt Maxxum mount lenses?
If not.. than I concur with Rick that Sony is shooting at very closely attached feet indeed.
Hopefully,. it's just another name for the existing mount. ??
**EDIT**
Almost a year on since that first announcement we have the new Sony Alpha DSLR-A100, a compact, ten megapixel (CCD) digital SLR with a (Konica) Minolta lens mount...
...The lens mount is to be called the 'Alpha mount' and Sony has announced no less than 22 lenses which will carry the Sony Alpha branding (although many are based on existing Minolta lenses).
Phew!
Also note.. (shades of Beta
) Htat this Sony Camera does NOT have a slot for Memory stick! CF is the only slot built in...
Just so that someones head wouldn't role though I;m sure,. Sony is including a Memory Stick to CF card adapter..
Really this looks like Sony is learning.. (slowly) by avoiding there dumbass Memory Stick.
