The lack of news is due to the fact there isn't going to be one. 😎
Intel has not released any updated chipsets for apple to use and improve their MBPs so they're just standing pat. Apple typically only updates their MBPs once a year, but have on rare occasions slipped through a small spec update when there's a chipset available from intel.
If you need (or want) a computer now, I'd say go and buy it, since we'll probably not see anything until the fall if not later, due to the delay in Broadwell.
