I don't know where you get all those weird ideas from.

Everybody know that WP7 was CE based.

One of many sources:

Windows Phone 7 is the successor to Microsoft's line of Windows Mobile 
phone operating systems. It's based on the Windows CE 6 kernel, like the 
Zune HD, while current versions of Windows Mobile are based on Windows 
CE 5.

There has been some debate whether WP7 was actually using a pre-release
of Windows CE 7.0 instead of Windows CE 6.0. But no doubt about the CE
part.

Not supporting 1 core may be true.

But MS publicly stated the support for up to 64 cores.

Microsoft is on stage at the Windows Phone Developer Summit offering us 
a bite of what's to come in Windows Phone 8, and one of the tastiest 
morsels may just be the noticeably more diverse hardware it will 
support. The new platform won't just support dual-core processors -- it 
will support as many as 64 cores, should such massively parallel chips 
come to exist in the platform's lifetime.
