I have no idea! You and I have the same credibility as our state media, as they echo Biden spokepeople and Biden himself, who also have absolutely no idea what Putin is planning.
Seems very obvious to me what Putin will do. He's already recognized Donetsk and Lugansk as independent countries, which means that as far as Russia is concerned, they are no longer part of Ukraine. Those "republics" will ask for and receive Russian military aid, so Russia will oblige and move into those two states and, if necessary, battle the "foreign" Ukrainian military invaders with help from the separatist militia which will no longer be separatists. But Russia will not go farther than those too provinces/states/republics or whatever they might be called UNLESS other states in Ukraine make similar pleas which are accepted, and that's possible in the south which is also has a majority pro-Russian sentiment.
Putin moving into western Ukraine is of no interest to Putin as his military would be in hostile territory and incur casualties that will hurt him at home, and Putin knows this so he won't do that. The civil war in Ukraine that's been running for the last 8 years will end.
The Deep State will whine and cry about it, and impose sanctions, and life will go on.
