The news was reported by PreCentral and confirmed by The Verge, HP CEO Meg Whitman has called a meeting for tomorrow to discuss webOS. You may remember that exactly one month ago, Whitman said that there would be a decision made concerning the fate of webOS within "three to four weeks".
Whitman has said that webOS would require a significant investment in order to make it successful, and HP has already spent quite a bit on it without showing that it can make the platform successful even with investment. With luck, we'll know tomorrow what the fate will be, and we'll bring it to you.
