In short: No, the old Commodore went bankrupt and never came
back. The new Commodore you see now is a company that bought the
naming rights. They are trying to make a buck on retro-people by
designing computer cases that look like the old Commodore ones.
There is even an effort similar to this for the Amiga brand, you
will be able to buy 'modern' versions of the Commodore Amiga
systems, which is nothing more than a generic case with a PC
inside, and there is even talk of a Linux OS with a WorkBench
theme.
So basically, if you are looking for the old Commodore, you can
still buy used stuff on ebay, or simply run an emulator. What you
might be interested in is checking www.pouet.net for demoscene
releases, people still actually make software for the Commodore
machines and release it every now and then.
Also, if you like the SID music of the Commodore, you might want
to check out the High Voltage Sid Collection; see links
There are still large Commodore and Amiga communities around on
the IRC and web forums, you might want to keep an eye out for those
if you are interested in reconnecting with the community. They will
also be able to answer most questions you might have about how to
best find hardware/software.
For example vesalia and amigakit has some interesting products,
for example a joystick with a built-in C64.
