Chinese phone maker vivo started teasing the launch of the upcoming X300 series last month. One of them even includes its launch date in its home market. More recently, the phones have also appeared in the SIRIM database. This just about confirms that they will be launching locally.
Both the vivo X300 and X300 Pro were granted SIRIM approval late last week. Worth noting that the former is accompanied by the model number of V2515, while the latter gets tagged with V2514. Either way, while this points at a local launch at some point, the specifics remain known only to the company.

Going over what we know of them so far, both the vivo X300 and X300 Pro will be powered by a MediaTek Dimensity 9500 chipset. The Pro model is also claimed to be getting a Satellite Edition, which features 16GB RAM, 1TB UFS 4.1 four-lane storage, a 6,510mAh battery, and VS1 and V3+ chips. Prior leaks have pointed to either a 200MP main, a 50MP wide-angle, and a 50MP 3x telephoto combination, or a 50MP main, a 50MP wide-angle, and a 200MP periscope telephoto combo.
At any rate, details of the phones themselves will be clear next week when they get officially announced. As for when will they be launched locally, the wait may be as soon as a month. On the flip side, it could take until early next year.
