It's thiner and lighter than Seeeduino v1.1,so better for some small project!
Seeeduino v2.1 will be released once we got C328,that may take about 1 month... SO .just wait... :-[
Can`t wait for Seeeduino V3.1 with the atmega645 !!!
How about adding a ARM7 or ARM9 to Seeeduino.LOL
Nice, I'll probaly have to purchase one of these when avalible. It's pretty clear that the 328 will become the 'base' chip for the Arduino platform for the near future and good to see some vendors driving towards that goal.

@retrolefty, 328 IS the base chip for the Arduino platform.
From the Arduino blog:
Arduino Duemilanove upgraded to the ATmega328
February 28th, 2009We're very happy to announce that the Arduino Duemilanove has been upgraded to a more powerful microcontroller: the ATmega328. It's fully compatible with the previous ATmega168, but with twice the memory. That includes flash memory for storing sketches (32 KB instead of 16 KB), RAM for holding variables (2KB instead of 1KB) and EEPROM for saving data when turning off the board (1 KB instead of 512 bytes). We've also raised the speed (in the bootloader) for uploading new sketches from 19200 baud to 57600 baud.
Thanks to some tough negotiating by Gianluca Martino of Arduino and Smart Projects, this won't raise the price of the board. Look for distributors to roll out the upgraded boards soon. Current Duemilanove or other Arduino boards can be upgraded by replacing the ATmega168 with a bootloaded ATmega328 (you'll need to buy a pre-bootloaded one or use a hardware programmer). Be sure to select “Arduino w/ ATmega328[ch8243] from the Tools > Boards menu.
and the Arduino Duemilanove boards with the ATmega328 microcontroller are already shipping from distributors:

Save that for v 4.1 , There is also Sam 7 and Sam 9 etc .
There are with upto 512k flash and 64k ram onboard , nice for a form of embedded linux .
DC Current for 3.3V Pin 500 mA
I'm a little worried about this one. It's a sort of dangerous incompatibility between Seeeduino and other diecimila-like boards; you might design a shield that works fine with a Seeeduino but fries the FTDI chip on an official board 
Hi westfw,
We add a chip(1117-3.3) which can drive 500mA @3.3v.
The FTDI's 3.3v out is not connect .
And we will test new functions with atmega168, until atmega328 comes.
If necessary v2.11 will be worked out.

I think westfw's point was that it would be possible to design shields that would work on a Seeeduino but would break an official Arduino board due to too much current draw.
Thus the Seeeduino would become "less than compatible" due to adding a feature.

Thanks for everyone's advice. we will fully test the new board ,try our best to make it better.
Will it have pin holes for FTDI bitbang programming?
EDITED. Well, I guess it doesn't make sense since the microcontroller cannot be replaced.
Adding in a separate 3.3V Vreg was a customer request on Seeedstudio's forums. This is a good feature for anyone doing a 3.3V project.
However, I can see the possibility of a problem, if someone developed and tested solely on this board. But this type of problem could occur from any board that extends the original Arduino's features. (This clone will also have a Mega 328 - so the designer knows its a custom board from step #1.)
Perhaps they could add a selector switch to toggle the 3.3V supply. One setting uses the new VReg and the other uses the FTDI 3.3V supply. The best of both worlds - and they get to add another cool switch.
Here is another pic of seeeduino V2.1. You can see the switchs were changed to bigger ones, which is better for the feel.
