The sweet spot is about 3-4 times the price for 10 times the bandwidth. Right now 10GBase-T isn't even close at 30x.
As the presentation indicates there are genuine use cases in offices and, in time, homes, for 2.5Gb and 5Gb. The idea that it's because incremental upgrades are more profitable seems strange given it's not incremental, 10Gb has already been released, it's just too expensive for the applications that may use it.
EDIT: I glossed entirely over something else quite obvious, too. The vast majority of cabling is Cat 5. 10Gbase-T doesn't run so well on most Cat 5, so something that will allow upgraded bandwidth without requiring changing out of all cables in offices is very desirable.

10gbit is out there but not aimed at the consumer market. As a consumer product 2.5gbit first makes sense.
Look at across the entire hardware space and you see the practice is incremental upgrades, from smartphones to computer components.
No way do hardware vendors release the best they have to offer, they always keep something in the pocket to get your money another day.
As an example intel have been making 16 core cpu's for years, yet we only got their first consumer 8 core cpu earlier this year.
