I actually got this a couple of days ago in my email but had not had chance to read more details. But the new MovableType hosting has had more details and prices released.
Looking at the details I certainly wouldn't want the basic plan as it only limits you to one blog and it looks like you'd be stuck with a design template someone else has written (so your page looks like everyone elses page!). I think for those of us bloggers, who are already using MovableType and more than the default installation would need the Plus installation, but if you need more than 3 blogs or do design work with MT then you'd need the Pro version, but at $15 a month, thats way more than the hosting at hasweb (although with hasweb you do have to install MT yourself (but its not that difficult))
I'm waiting for Movable Type Pro, which should have a number o TypePad's features in it.
