Considering that WM6.5 was suppose to appear in beta before Windows 7 Beta its about time they announced this.
Regarding someones comments about about the tytn II phone, ive ran wm6 and 6.1 on my phone, i did notice a speed up with wm6.1 over 6 however it was never slow with 6.
Im not sure what rom your using, possibly its a badly cooked rom or packed full of your operators bloat thats not needed personally i jailbrake the operators customisation packs on my phones and run the stock rom.
I do agree it would be nice to see windows mobile 7 offering some nicer visual updates, but to me windows mobile has always been the most flexible, im happy to do away with all the eye candy for something that does the job properly and thats why i love windows mobile.
There simply hasnt been a time where ive though um would be helpful if my phone did x where i couldnt either write/mod an app to do it or find some software that did.
it makes me laugh all the tree hugging and possibly linux fan boys who just flame something for being microsoft, im not saying microsoft is always no 1 or the best but until the google os (android) grows a little older i wont even dream of leaving windows mobile.
