Somewhat, yes. Whatever votes they get, they mostly take over from SPD and Greens, though. All three of those parties moved to the right significantly, so even if there is a majority for the three of them together some day and if (the bigger one) SPD and Greens enter into a coalition with Die Linke, my impression is that it won’t be that different from the SPD/Greens coalition at the turn of the century or the SPD/Greens/Liberals coalition in the past election cycle: center-left at best, but far from substantial improvements to our economy, social security system or imperialist foreign policy. :(
