T9300 is unlikely. all cases point to T8300- the 2.4GHz with 3MB L2. pricepoints are equivalent with the current T7500 2.2GHz 4MB and lenovo, dell offer these as equivalent upgrades, while T9300 is not a free upgrade. just don't get your hopes up. vram upgrade is possible but no definitive word atm. overall, not a significant upgrade unless things like multitouch trackpad are important to you.
