I've been gone a few days from the board, so I am suprised no one has mentioned this. Here is a summary from Architosh:
<BLOCKQUOTE>quote:</font><HR> It appears from this road map that the next Motorola "G-something" processor will be a G4, its model number being MPC7457, with a MHz range between 867-1833MHz. This chip is based on a SOI (silicon on insulator), .13micron process and appears planned for sometime in 2003. The MPC7457-RM chip, planned for 2004 is more mysterious and includes RapidIO.<HR></BLOCKQUOTE>
Rumour has it this will be a G4+ or something along those lines. An updated G4 with a true DDR bus, a fast bus, and up wo 1.8 GHz.
On the downside, by that point we will still be anywhere from 1 to 2.5 GHz behind in terms of speed (and before you start, I mean the numbers not the performance). But still, hopefully Moto can pull this out of their butt and we will have a new low end processor, right below the IBM GPUL.
