New WES 7 SP1 CTP

I just downloaded wes 7 sp1 DVD from Microsoft connect. After installed 3 discs (toolkit , 32 bit IBW, 64 bit IBW) to wes 7 system then opened previous wes 7's xml file. most of component treated as unknown package, unknown component. So I use ICE to create image, it seems most of items same as wes 7, it recognize capella and added a lot of update patches. I create IBW iamge from Answer file to USB flash drive. So far so good, the image creatd with auto answer USB flash drive. I will check the difference later.
