Looks like the warmed over Rebel is still holding it's own though.

Nikon secures top position in the Japanese DSLR market

Nikon Corp., Tokyo, Japan, grabbed the top position in the Japanese
DSLR market in December with a market share of 47 percent, thanks to
strong sales of D80 and the new D40, according to the latest report by
BCN. BCN is a market research firm constantly monitoring POS data from
2,680 stores operated by 23 contracted major retailing companies.

 Canon Inc. gave up the lead to Nikon with a market share of 35
percent. Pentax and Sony followed with a market share of 10 percent
and 6 percent, respectively. Canon was the constant leader in the
Japanese DSLR market, for example with a market share of 45 percent in
July and 48 percent in September last year, followed by Nikon (37
percent in July and 33 percent in September) and Pentax (10 percent in
July and 8 percent in September).

 In terms of by-model share, however, Canon's Digital Kiss X (digital
Rebel XTi) kept the top spot for 13 weeks consecutively with a 27.3
percent market share in December, followed by Nikon's D80 (16.3
percent), D40 (15.5 percent) and D200 (9.1 percent), reports JPEA
International PEN News Weekly.

 Many industry watchers were skeptical when Nikon announced the D40,
saying it would be difficult for Nikon to sell as it hoped in the
market where DSLRs featuring 10-megapixel or more pixel counts are the
mainstream. Contrary to the popular belief, however, the D40
apparently made a good start in the Japanese market, reports PEN News
Weekly.
