Well, the Pentium name has been very strong for Intel - even with the Core ranges being popular, there are still people who ask for an "Intel Pentium" and Intel must know this.
These new Pentium's won't be the top end parts, but they are named Pentium nonetheless. Expreview has a diagram of the new chips, with a tonne of information and specs to get all nasty with.
All four models are dual-core processors, without HT. Three of the four models are 65W TDP parts, the fourth is a "T" model with a 35W TDP. There's also news floating around that the H61 chipset will be the replacement for the LGA775 platform over time - although that is not meant to happen until the end of 2011, if not the beginning of 2012.
Hit up the source for more info, most of it being on the included picture - interesting stuff! It's good to see the Pentium name is still strong.
