It looks like the successor to the HP Mini Note 2133 is coming sooner than expected, named the HP Mini Note 2134. Product part information for batteries for the Mini Note 2134 were discovered on some sites.

The externals will probably remain the same but it could come with a 10-inch glossy display (please at 1280 x 768!), Intel Atom processor and a 6-cell battery. I think most people with the Mini 1000 are expecting a 6-cell to arrive from HP early this year anyway
