NTT DoCoMo's CTIA 2008 booth tour, hello Super 3G

NTT DoCoMo had a pretty lavish setup here at CTIA, though no new product caught our eye. However, they did have the results from the Super 3G / LTE shenanigans they've been up to in Japan, and the results show serious speed. They're touting Super 3G / LTE as 3.9G -- wow, that extra .4G seems to be making a huge diff -- with theoretical downlink and uplink speeds listed as 70Mbps and 300Mbps. Compared to current HSPA speeds this is a monstrous leap, can you say kiss your cable goodbye? Hit the gallery below for more pics.

Shouldn't downlink be 300Mbps instead of 70?

Can someone please enlighten us on some of this?
AFAIK, the 3GPP line goes like this:
UMTS -> HSPA(HSDPA/HSUPA) -> "HSPA+" -> HSOPA (emphasis on the letter 'O')
Japan's "Super 3G" is just "HSOPA", right? And what exactly is "LTE"? Is "LTE" just a general term for 4G technology, basically referring to HSOPA and whatever comes after it? And if everyone else calls LTE/HSOPA 4G, why is japan calling HSOPA ("Super3G") 3.9G ?

WTF?
