This Could All Be Rendered Moot
On the off chance that the rumours are correct, you can take a peek at what might just be the new Surface Pro 8. There is not much difference between the purported new model and the previous, which in the current market is to be expected. The biggest change that everyone is hoping for would be availability, and unfortunately there is no way to know if the supply will be large enough to satisfy demand.
As with many ultraportables of this size, USB-A has been removed with Microsoft choosing a pair of USB-C Thunderbolt 4 connectors. The NVMe SSD will be user replaceable, which is always a wonderful thing to see, especially if Microsoft opts to install a QLC SSD inside to reduce costs. The Surface Pro 4 will use Intel’s Tiger Lake series of APUs to power it.
There is one other possible change which would break from years of tradition and as such seems less likely than the previously mentioned challenges. The rumour is that the new Surface Pro 4 has a 13″ screen, larger than any of the other recent Intel powered models. If true, this could spell an end for compatibility with previous accessories which worked with previous models. On the other hand the 120Hz upgrade seems quite reasonable.
The renders show a Surface with a design similar to the current Surface Pro 7, just with a notably larger screen and smaller bezels than the current Surface Pro 7. Take this with a larger grain of salt the "screens" in these press renders are often superimposed on the devices after the fact.
